returns the size of a block of encrypted/decrypted ciphertext in bytes.
The result depends on the public key algorithm, key size and padding scheme. In general the input to decrypt() or encrypt() must be less than or equal to this block size. The output of decrypt() or encrypt() is always equal to this block size.
Implements SiAlgorithm.

virtual |
returns the type of public key algorithm computed by this object
Implements SiAlgorithm.

virtual |
creates a signature.
inputHash | array of hash key bytes that are to be signed |
inputHashSize | length of hash key array in bytes |
inputHashAlgorithm | MAC algorithm used for creation of hash key. Required for creation of PKCS#1 RSA signature padding. |
outputSignature | pointer to array of at least getSize() which must be allocated by caller. |
outputSignatureSize | returns the number of bytes written to outputSignature. |
Implements SiAlgorithm.
|
virtual |
verifies a signature.
inputHash | array of bytes containing hash key to be verified against signature |
inputHashSize | length of hash key array in bytes |
inputHashAlgorithm | MAC algorithm used for creation of hash key. Required for creation of PKCS#1 RSA signature padding. |
inputSignature | array of bytes containing signature to be verified |
inputSignatureSize | length of signature array in bytes |
verified | returns whether the signature was successfully verified |
