Methods in io.jsonwebtoken that throw InvalidKeyException

Key Signature Algorithm

Modifier and Type	Method and Description
void	SignatureAlgorithm.assertValidSigningKey(Key key) Returns quietly if the specified key is allowed to create signatures using this algorithm according to the JWT JWA Specification (RFC 7518) or throws an InvalidKeyException if the key is not allowed or not secure enough for this algorithm.
void	SignatureAlgorithm.assertValidVerificationKey(Key key) Returns quietly if the specified key is allowed to verify signatures using this algorithm according to the JWT JWA Specification (RFC 7518) or throws an InvalidKeyException if the key is not allowed or not secure enough for this algorithm.
static SignatureAlgorithm	SignatureAlgorithm.forSigningKey(Key key) Returns the recommended signature algorithm to be used with the specified key according to the following heuristics:
JwtBuilder	JwtBuilder.signWith(Key key) Signs the constructed JWT with the specified key using the key's recommended signature algorithm, producing a JWS.
JwtBuilder	JwtBuilder.signWith(Key key, SignatureAlgorithm alg) Signs the constructed JWT with the specified key using the specified algorithm, producing a JWS.
JwtBuilder	JwtBuilder.signWith(SignatureAlgorithm alg, byte[] secretKey) Deprecated. as of 0.10.0: use Keys.hmacShaKeyFor(bytes) to obtain the Key and then invoke JwtBuilder.signWith(Key) or JwtBuilder.signWith(Key, SignatureAlgorithm). This method will be removed in the 1.0 release.
JwtBuilder	JwtBuilder.signWith(SignatureAlgorithm alg, Key key) Deprecated. since 0.10.0: use JwtBuilder.signWith(Key, SignatureAlgorithm) instead. This method will be removed in the 1.0 release.
JwtBuilder	JwtBuilder.signWith(SignatureAlgorithm alg, String base64EncodedSecretKey) Deprecated. as of 0.10.0: use JwtBuilder.signWith(Key) or JwtBuilder.signWith(Key, SignatureAlgorithm) instead. This method will be removed in the 1.0 release.
