Javascript AES-CBC: PKCS7 Padding broken for 16 bytes long blocks (and multiples)

Posted on Aug 9, 2009 by Massive Wombat

When encrypting 16 bytes long blocks (and multiples of 16 bytes) of plaintext with the Javascript version of SlowAES/CBC the padding block is not appended.

PKCS7 needs a full 16-bytes padding block made of 0x10 added to the plaintext before encryption in such case.

Thanks for the library! stefano
