Method Detail

decrypt

byte[] decrypt(JWEHeader header,
               Base64URL encryptedKey,
               Base64URL iv,
               Base64URL cipherText,
               Base64URL authTag)
        throws JOSEException

Decrypts the specified cipher text of a JWE Object.

Parameters:

header - The JSON Web Encryption (JWE) header. Must specify a supported JWE algorithm and method. Must not be null.

encryptedKey - The encrypted key, null if not required by the JWE algorithm.

iv - The initialisation vector, null if not required by the JWE algorithm.

cipherText - The cipher text to decrypt. Must not be null.

authTag - The authentication tag, null if not required.

Returns:

The clear text.

Throws:

JOSEException - If the JWE algorithm or method is not supported, if a critical header parameter is not supported or marked for deferral to the application, or if decryption failed for some other reason.
