ncryption method: 128-bit AES with CBC mode.

Key (in hex): 00112233445566778899aabbccddeeff (known only to Bob)

Ciphertext (C1): bef65565572ccee2a9f9553154ed9498 (known to both)

IV used on P1 (known to both)

(in ascii): 1234567890123456

(in hex) : 31323334353637383930313233343536

Next IV (known to both)

(in ascii): 1234567890123457

(in hex) : 31323334353637383930313233343537
