Normally, a block encryption algorithm (AES, Blowfish, DES, RC2, etc.) 5.00/5 (1 vote) See more: C#. Since AES is a symmetric encrypton algorithm, the key is private and needs to be known only by the two communicating parties. If I found two $5 bills on the ground, would it be acceptable to say "$10 are on the ground"? HsAudio C Source Library is an audio software library implemented in C language. * + a demo code example (zip, 5Kb) Note it is AES-256, not AES-128.
