Uses of EncryptionException in org.owasp.esapi.crypto

Methods in org.owasp.esapi.crypto that throw EncryptionException

Modifier and Type	Method and Description
byte[]	CipherText.asPortableSerializedByteArray() Return this CipherText object as a portable (i.e., network byte ordered) serialized byte array.
SecretKey	KeyDerivationFunction.computeDerivedKey(SecretKey keyDerivationKey, int keySize, String purpose) The method is ESAPI's Key Derivation Function (KDF) that computes a derived key from the keyDerivationKey for either encryption / decryption or for authentication.
static SecretKey	CryptoHelper.computeDerivedKey(SecretKey keyDerivationKey, int keySize, String purpose) Deprecated. UseKeyDerivationFunction instead. This method will be removed as of ESAPI release 2.1 so if you are using this, please change your code.
static CipherText	CipherText.fromPortableSerializedBytes(byte[] bytes) Create a CipherText object from what is supposed to be a portable serialized byte array, given in network byte order, that represents a valid, previously serialized CipherText object using CipherText.asPortableSerializedByteArray().
static SecretKey	CryptoHelper.generateSecretKey(String alg, int keySize) Generate a random secret key appropriate to the specified cipher algorithm and key size.
String	CryptoToken.getToken() Return the new encrypted token as a base64-encoded string, encrypted with the specified SecretKey with which this object was constructed.
String	CryptoToken.getToken(SecretKey skey) Return the new encrypted token as a base64-encoded string, encrypted with the specified SecretKey which may be a different key than what the token was originally encrypted with.
void	CipherText.setCiphertext(byte[] ciphertext) Set the raw ciphertext.
void	CipherText.setIVandCiphertext(byte[] iv, byte[] ciphertext) Set the IV and raw ciphertext.
String	CryptoToken.updateToken(int additionalSecs) Update the (current) expiration time by adding the specified number of seconds to it and then re-encrypting with the current SecretKey that was used to construct this object.
