Encrypt a byte string.
- Parameters:
-
rng a RandomNumberGenerator derived class plaintext the plaintext byte buffer plaintextLength the size of the plaintext byte buffer ciphertext a byte buffer to hold the encrypted string parameters additional configuration options
- Precondition:
CiphertextLength(plaintextLength) != 0ensures the plaintext isn't too large-
COUNTOF(ciphertext) == CiphertextLength(plaintextLength)ensures the output byte buffer is large enough.
- See also:
- PK_Decryptor
Implements PK_Encryptor.

Create a new encryption filter.
- Note:
- The caller is responsible for deleting the returned pointer.
- Encoding parameters should be passed in the "EP" channel.

| virtual size_t PK_CryptoSystem::FixedCiphertextLength | ( | ) | const [inline, virtual, inherited] |
return fixed ciphertext length, if one exists, otherwise return 0
- Note:
- "Fixed" here means length of ciphertext does not depend on length of plaintext. It usually does depend on the key length.

| virtual std::string Algorithm::AlgorithmName | ( | ) | const [inline, virtual, inherited] |
Provides the name of this algorithm.
- Returns:
- the standard algorithm name
The standard algorithm name can be a name like AES or AES/GCM. Some algorithms do not have standard names yet. For example, there is no standard algorithm name for Shoup's ECIES.
- Note:
- AlgorithmName is not universally implemented yet
Reimplemented in Adler32, CCM_Base, CRC32, ClassNullRNG, AuthenticatedSymmetricCipher, DH_Domain< GROUP_PARAMETERS, COFACTOR_OPTION >, EAX_Base, StreamTransformationFilter, HashFilter, HashVerificationFilter, AuthenticatedDecryptionFilter, SignerFilter, SignatureVerificationFilter, GCM_Base, HMAC< T >, RDRAND, RDSEED, SHA3, BitBucket, and VMAC_Base.

| virtual Clonable* Clonable::Clone | ( | ) | const [inline, virtual, inherited] |
Copies this object.
- Returns:
- a copy of this object
- Exceptions:
-
NotImplemented
- Note:
- this is not implemented by most classes
