All Implemented Interfaces:

ICryptoContext

Direct Known Subclasses:

JsonWebKeyLadderExchange.AesKwJwkCryptoContext

Enclosing class:

JsonWebKeyLadderExchange

public abstract static class JsonWebKeyLadderExchange.JwkCryptoContext
extends Object
implements ICryptoContext

A specialized crypto context for wrapping and unwrapping JSON web keys.

Implementations of this class must add and remove padding to the JSON web key string representation's binary encoding for compatibility with the wrapping algorithm used.

public JsonWebKeyLadderExchange.JwkCryptoContext()

Method Detail

encrypt

public byte[] encrypt(byte[] data)
               throws MslCryptoException

Description copied from interface: ICryptoContext

Encrypts some data.

Specified by:

encrypt in interface ICryptoContext

Parameters:

data - the plaintext.

Returns:

the ciphertext.

Throws:

MslCryptoException - if there is an error encrypting the data.

decrypt

public byte[] decrypt(byte[] data)
               throws MslCryptoException

Description copied from interface: ICryptoContext

Decrypts some data.

Specified by:

decrypt in interface ICryptoContext

Parameters:

data - the ciphertext.

Returns:

the plaintext.

Throws:

MslCryptoException - if there is an error decrypting the data.

sign

public byte[] sign(byte[] data)
            throws MslCryptoException

Description copied from interface: ICryptoContext

Computes the signature for some data. The signature may not be a signature proper, but the name suits the concept.

Specified by:

sign in interface ICryptoContext

Parameters:

data - the data.

Returns:

the signature.

Throws:

MslCryptoException - if there is an error computing the signature.

verify

public boolean verify(byte[] data,
                      byte[] signature)
               throws MslCryptoException

Description copied from interface: ICryptoContext

Verifies the signature for some data. The signature may not be a signature proper, but the name suits the concept.

Specified by:

verify in interface ICryptoContext

Parameters:

data - the data.

signature - the signature.

Returns:

true if the data is verified, false if validation fails.

Throws:

MslCryptoException - if there is an error verifying the signature.
