    NOTE: this method will be removed before version 1.0
    
    Sets the signing key used to verify any discovered JWS digital signature. If the specified JWT string is not a JWS (no signature), this key is not used.
    Note that this key MUST be a valid key for the signature algorithm found in the JWT header (as the alg header parameter).
    
    This method overwrites any previously set key.

JwtParser setSigningKey(String base64EncodedSecretKey)
```
    Deprecated. see JwtParserBuilder.setSigningKey(String). To construct a JwtParser use the corresponding builder via Jwts.parserBuilder(). This will construct an immutable JwtParser.
    NOTE: this method will be removed before version 1.0
    
    Sets the signing key used to verify any discovered JWS digital signature. If the specified JWT string is not a JWS (no signature), this key is not used.
    Note that this key MUST be a valid key for the signature algorithm found in the JWT header (as the alg header parameter).
    
    This method overwrites any previously set key.
    
    This is a convenience method: the string argument is first BASE64-decoded to a byte array and this resulting byte array is used to invoke setSigningKey(byte[]).
    
    Deprecation Notice: Deprecated as of 0.10.0, will be removed in 1.0.0
    
    This method has been deprecated because the key argument for this method can be confusing: keys for cryptographic operations are always binary (byte arrays), and many people were confused as to how bytes were obtained from the String argument.
    
    This method always expected a String argument that was effectively the same as the result of the following (pseudocode):
    
    String base64EncodedSecretKey = base64Encode(secretKeyBytes);
    
    However, a non-trivial number of JJWT users were confused by the method signature and attempted to use raw password strings as the key argument - for example setSigningKey(myPassword) - which is almost always incorrect for cryptographic hashes and can produce erroneous or insecure results.
    
    See this StackOverflow answer explaining why raw (non-base64-encoded) strings are almost always incorrect for signature operations.
    
    Finally, please use the setSigningKey(Key) instead, as this method and the byte[] variant will be removed before the 1.0.0 release.
    
    Parameters:
    base64EncodedSecretKey - the BASE64-encoded algorithm-specific signature verification key to use to validate any discovered JWS digital signature.
    
    Returns:
    the parser for method chaining.

    Deprecated. see JwtParserBuilder.setSigningKey(Key). To construct a JwtParser use the corresponding builder via Jwts.parserBuilder(). This will construct an immutable JwtParser.

    Sets the signing key used to verify any discovered JWS digital signature. If the specified JWT string is not a JWS (no signature), this key is not used.
    Note that this key MUST be a valid key for the signature algorithm found in the JWT header (as the alg header parameter).

  - setSigningKeyResolver
```
@Deprecated
JwtParser setSigningKeyResolver(SigningKeyResolver signingKeyResolver)
```
    Deprecated. see JwtParserBuilder.setSigningKeyResolver(SigningKeyResolver). To construct a JwtParser use the corresponding builder via Jwts.parserBuilder(). This will construct an immutable JwtParser.
    NOTE: this method will be removed before version 1.0
    Sets the SigningKeyResolver used to acquire the signing key that should be used to verify a JWS's signature. If the parsed String is not a JWS (no signature), this resolver is not used.
    Specifying a SigningKeyResolver is necessary when the signing key is not already known before parsing the JWT and the JWT header or payload (plaintext body or Claims) must be inspected first to determine how to look up the signing key. Once returned by the resolver, the JwtParser will then verify the JWS signature with the returned key. For example:
```
 Jws<Claims> jws = Jwts.parser().setSigningKeyResolver(new SigningKeyResolverAdapter() {
         @Override
         public byte[] resolveSigningKeyBytes(JwsHeader header, Claims claims) {
             //inspect the header or claims, lookup and return the signing key
             return getSigningKey(header, claims); //implement me
         }})
     .parseClaimsJws(compact);
 
```
    A SigningKeyResolver is invoked once during parsing before the signature is verified.
    
    This method should only be used if a signing key is not provided by the other setSigningKey* builder methods.
    Parameters:
    signingKeyResolver - the signing key resolver used to retrieve the signing key.
    
    Returns:
    the parser for method chaining.

  - setCompressionCodecResolver
```
@Deprecated
JwtParser setCompressionCodecResolver(CompressionCodecResolver compressionCodecResolver)
```
    Deprecated. see JwtParserBuilder.setCompressionCodecResolver(CompressionCodecResolver). To construct a JwtParser use the corresponding builder via Jwts.parserBuilder(). This will construct an immutable JwtParser.
    NOTE: this method will be removed before version 1.0
    
    Sets the CompressionCodecResolver used to acquire the CompressionCodec that should be used to decompress the JWT body. If the parsed JWT is not compressed, this resolver is not used.
    NOTE: Compression is not defined by the JWT Specification, and it is not expected that other libraries (including JJWT versions < 0.6.0) are able to consume a compressed JWT body correctly. This method is only useful if the compact JWT was compressed with JJWT >= 0.6.0 or another library that you know implements the same behavior.
    
    Default Support
    
    JJWT's default JwtParser implementation supports both the DEFLATE and GZIP algorithms by default - you do not need to specify a CompressionCodecResolver in these cases.
    
    However, if you want to use a compression algorithm other than DEF or GZIP, you must implement your own CompressionCodecResolver and specify that via this method and also when building JWTs.
    
    Parameters:
    compressionCodecResolver - the compression codec resolver used to decompress the JWT body.
    
    Returns:
    the parser for method chaining.

    NOTE: this method will be removed before version 1.0
    
    Perform Base64Url decoding with the specified Decoder
    JJWT uses a spec-compliant decoder that works on all supported JDK versions, but you may call this method to specify a different decoder if you desire.
    
    Parameters:
    base64UrlDecoder - the decoder to use when Base64Url-decoding
    
    Returns:
    the parser for method chaining.

```
    Deprecated. see JwtParserBuilder.deserializeJsonWith(Deserializer) )}. To construct a JwtParser use the corresponding builder via Jwts.parserBuilder(). This will construct an immutable JwtParser.
    NOTE: this method will be removed before version 1.0
    
    Uses the specified deserializer to convert JSON Strings (UTF-8 byte arrays) into Java Map objects. This is used by the parser after Base64Url-decoding to convert JWT/JWS/JWT JSON headers and claims into Java Map objects.
    If this method is not called, JJWT will use whatever deserializer it can find at runtime, checking for the presence of well-known implementations such Jackson, Gson, and org.json. If one of these is not found in the runtime classpath, an exception will be thrown when one of the various parse* methods is invoked.
    
    Parameters:
    deserializer - the deserializer to use when converting JSON Strings (UTF-8 byte arrays) into Map objects.
    
    Returns:
    the parser for method chaining.

  - isSigned
```
boolean isSigned(String jwt)
```
    Returns true if the specified JWT compact string represents a signed JWT (aka a 'JWS'), false otherwise.
    Note that if you are reasonably sure that the token is signed, it is more efficient to attempt to parse the token (and catching exceptions if necessary) instead of calling this method first before parsing.
    
    Parameters:
    jwt - the compact serialized JWT to check
    
    Returns:
    true if the specified JWT compact string represents a signed JWT (aka a 'JWS'), false otherwise.

```
    Parses the specified compact serialized JWT string based on the builder's current configuration state and returns the resulting JWT or JWS instance.
    This method returns a JWT or JWS based on the parsed string. Because it may be cumbersome to determine if it is a JWT or JWS, or if the body/payload is a Claims or String with instanceof checks, the parse(String,JwtHandler) method allows for a type-safe callback approach that may help reduce code or instanceof checks.
    
    Parameters:
    jwt - the compact serialized JWT to parse
    
    Returns:
    the specified compact serialized JWT string based on the builder's current configuration state.
    
    Throws:
    
    MalformedJwtException - if the specified JWT was incorrectly constructed (and therefore invalid). Invalid JWTs should not be trusted and should be discarded.
    
    SignatureException - if a JWS signature was discovered, but could not be verified. JWTs that fail signature validation should not be trusted and should be discarded.
    
    ExpiredJwtException - if the specified JWT is a Claims JWT and the Claims has an expiration time before the time this method is invoked.
    
    IllegalArgumentException - if the specified string is null or empty or only whitespace.

    Parses the specified compact serialized JWT string based on the builder's current configuration state and invokes the specified handler with the resulting JWT or JWS instance.
    If you are confident of the format of the JWT before parsing, you can create an anonymous subclass using the JwtHandlerAdapter and override only the methods you know are relevant for your use case(s), for example:
```
 String compactJwt = request.getParameter("jwt"); //we are confident this is a signed JWS

 String subject = Jwts.parser().setSigningKey(key).parse(compactJwt, new JwtHandlerAdapter<String>() {
     @Override
     public String onClaimsJws(Jws<Claims> jws) {
         return jws.getBody().getSubject();
     }
 });
 
```
    If you know the JWT string can be only one type of JWT, then it is even easier to invoke one of the following convenience methods instead of this one:
    Type Parameters:
    T - the type of object returned from the handler
    Parameters:
    jwt - the compact serialized JWT to parse
    handler - the handler to invoke when encountering a specific type of JWT
    
    Returns:
    the result returned by the JwtHandler
    
    Throws:
    
    MalformedJwtException - if the specified JWT was incorrectly constructed (and therefore invalid). Invalid JWTs should not be trusted and should be discarded.
    
    SignatureException - if a JWS signature was discovered, but could not be verified. JWTs that fail signature validation should not be trusted and should be discarded.
    
    ExpiredJwtException - if the specified JWT is a Claims JWT and the Claims has an expiration time before the time this method is invoked.
    
    IllegalArgumentException - if the specified string is null or empty or only whitespace, or if the handler is null.

    Parses the specified compact serialized JWT string based on the builder's current configuration state and returns the resulting unsigned plaintext JWT instance.
    This is a convenience method that is usable if you are confident that the compact string argument reflects an unsigned plaintext JWT. An unsigned plaintext JWT has a String (non-JSON) body payload and it is not cryptographically signed.
    
    If the compact string presented does not reflect an unsigned plaintext JWT with non-JSON string body, an UnsupportedJwtException will be thrown.
    
    Parameters:
    plaintextJwt - a compact serialized unsigned plaintext JWT string.
    
    Returns:
    the Jwt instance that reflects the specified compact JWT string.
    
    Throws:
    
    UnsupportedJwtException - if the plaintextJwt argument does not represent an unsigned plaintext JWT
    
    MalformedJwtException - if the plaintextJwt string is not a valid JWT
    
    SignatureException - if the plaintextJwt string is actually a JWS and signature validation fails
    
    IllegalArgumentException - if the plaintextJwt string is null or empty or only whitespace
    
    SignatureException

    Parses the specified compact serialized JWT string based on the builder's current configuration state and returns the resulting unsigned plaintext JWT instance.
    This is a convenience method that is usable if you are confident that the compact string argument reflects an unsigned Claims JWT. An unsigned Claims JWT has a Claims body and it is not cryptographically signed.
    
    If the compact string presented does not reflect an unsigned Claims JWT, an UnsupportedJwtException will be thrown.
    
    Parameters:
    claimsJwt - a compact serialized unsigned Claims JWT string.
    
    Returns:
    the Jwt instance that reflects the specified compact JWT string.
    
    Throws:
    
    UnsupportedJwtException - if the claimsJwt argument does not represent an unsigned Claims JWT
    
    MalformedJwtException - if the claimsJwt string is not a valid JWT
    
    SignatureException - if the claimsJwt string is actually a JWS and signature validation fails
    
    ExpiredJwtException - if the specified JWT is a Claims JWT and the Claims has an expiration time before the time this method is invoked.
    
    IllegalArgumentException - if the claimsJwt string is null or empty or only whitespace

    Parses the specified compact serialized JWS string based on the builder's current configuration state and returns the resulting plaintext JWS instance.
    This is a convenience method that is usable if you are confident that the compact string argument reflects a plaintext JWS. A plaintext JWS is a JWT with a String (non-JSON) body (payload) that has been cryptographically signed.
    
    If the compact string presented does not reflect a plaintext JWS, an UnsupportedJwtException will be thrown.
    
    Parameters:
    plaintextJws - a compact serialized JWS string.
    
    Returns:
    the Jws instance that reflects the specified compact JWS string.
    
    Throws:
