aes256EcbEncrypt is ECB encryption mode with AES-256 single block cipher.

The algorithm reference is : “Recommendation for Block Cipher Modes of Operation - Methods and Techniques” The implementation is modified for better performance.

Parameters:

plaintextStrm Input block stream text to be encrypted, each block is 128 bits.
endPlaintextStrm End flag of block stream plaintext, 1 bit.
cipherkeyStrm Input cipher key used in encryption, 256 bits.
ciphertextStrm Output encrypted block stream text, each block is 128 bits.
endCiphertextStrm End flag of block stream ciphertext, 1 bit.
