Cryptography HMAC Algorithm in VB.NET
Encryption types — MIT Kerberos Documentation Encryption types¶. Kerberos can use a variety of cipher algorithms to protect data. A Kerberos encryption type (also known as an enctype) is a specific combination of a cipher algorithm with an integrity algorithm to provide both confidentiality and integrity to data.

Authenticated Encryption with AES-CBC and HMAC-SHA The CBC-HMAC encryption process is as follows, or uses an equivalent set of steps: The secondary keys MAC_KEY and ENC_KEY are generated from the input key K as follows. Each of these two keys is an octet string. MAC_KEY consists of the initial MAC_KEY_LEN octets of K, in order. ENC_KEY consists of the final ENC_KEY_LEN octets of K, in order.
You should use HMAC for that. Attacker is some cases is able to encrypt message without knowing the key. For example Padding Oracle Attack may allow this. – pgolen May 12 '12 at 7:10 HMAC-SHA1 vs. AES - Cryptography Stack Exchange HMAC-SHA1 is not an encryption algorithm. It is a hashing function. Wikipedia and other sources are good at explaining what AES, HMAC, and SHA-1 are. In all honestly, you shouldn't be rolling your own crypto and if you know this little about crypto you probably shouldn't be developing this part of the application at all.

[Solved] How to encrypt and decrypt a string using hmac
Using Encryption to Secure a 7 Series FPGA Bitstream encryption key can only be programmed onto the device through the JTAG port. The 7 series device performs the reverse operation, decrypting the incoming bitstream during configuration. The 7 series FPGA AES encryption logic uses a 256-bit encryption key. The on-chip AES decryption logic cannot be used for any purpose other than bitstream
