AES Message Encryptor for SMS

Jan 2, 2017

New block cipher mode has been added. Earlier mode ECB has the disadvantage that identical plaintext blocks are encrypted into identical ciphertext blocks; thus, if used with a non-random and repetitive data it is vulnerable to crypt analysis as it is deterministic.
This has been now corrected and a new mode has been added called Cipher Block Chaining method(CBC), where in identical plaintext blocks are not encrypted into identical ciphertext blocks.

Note that CBC is not compatible with ECB.
