desEcbDecrypt is ECB decryption mode with DES 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:

ciphertextStrm	Input block stream to be decrypted, each block is 64 bits.
endCiphertextStrm	End flag of block stream ciphertext, 1 bit.
cipherkeyStrm	Input cipher key used in decryption, 64 bits for each key.
plaintextStrm	Output decrypted block stream text, each block is 64 bits.
endPlaintextStrm	End flag of block stream plaintext, 1 bit.
