Interface ICryptoContext

public interface ICryptoContext

A generic cryptographic context suitable for encryption/decryption, wrap/unwrap, and sign/verify operations.

Method Summary

byte[]	decrypt(byte[] data) Decrypts some data.
byte[]	encrypt(byte[] data) Encrypts some data.
byte[]	sign(byte[] data) Computes the signature for some data.
byte[]	unwrap(byte[] data) Unwraps some data.
boolean	verify(byte[] data, byte[] signature) Verifies the signature for some data.
byte[]	wrap(byte[] data) Wraps some data.

Method Detail

encrypt

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

Encrypts some data.

Parameters:

data - the plaintext.

Returns:

the ciphertext.

Throws:

MslCryptoException - if there is an error encrypting the data.

decrypt

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

Decrypts some data.

Parameters:

data - the ciphertext.

Returns:

the plaintext.

Throws:

MslCryptoException - if there is an error decrypting the data.

wrap

byte[] wrap(byte[] data)
            throws MslCryptoException

Wraps some data.

Parameters:

data - the plaintext.

Returns:

the wrapped data.

Throws:

MslCryptoException - if there is an error wrapping the data.

unwrap

byte[] unwrap(byte[] data)
              throws MslCryptoException

Unwraps some data.

Parameters:

data - the wrapped data.

Returns:

the plaintext.

Throws:

MslCryptoException - if there is an error unwrapping the data.

sign

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

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

Parameters:

data - the data.

Returns:

the signature.

Throws:

MslCryptoException - if there is an error computing the signature.

verify

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

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

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.
