AES Message Encryptor for SMS

4/1/2017

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.
