Encrypt a byte string.
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 |
CiphertextLength(plaintextLength) != 0
ensures the plaintext isn't too large COUNTOF(ciphertext) == CiphertextLength(plaintextLength)
ensures the output byte buffer is large enough. Implements PK_Encryptor.

Provides the name of this algorithm.
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.
Reimplemented in AuthenticatedSymmetricCipher, SignatureVerificationFilter, SignerFilter, AuthenticatedDecryptionFilter, HashVerificationFilter, HashFilter, StreamTransformationFilter, ClassNullRNG, BitBucket, RDSEED, DH_Domain< GROUP_PARAMETERS, COFACTOR_OPTION >, HMAC< T >, RDRAND, CRC32, GCM_Base, Adler32, EAX_Base, CCM_Base, SHA3, and VMAC_Base.
