I’m no chipher expert so I have a question.
Is AES (Rijndael) FIPS compliant with both 128 and 256 bit length?
Best answer by Blaine Williams
1. Name of Standard. Advanced Encryption Standard (AES) (FIPS PUB 197).
2. Category of Standard. Computer Security Standard, Cryptography.
3. Explanation. The Advanced Encryption Standard (AES) specifies a FIPS-approved cryptographic algorithm that can be used to protect electronic data. The AES algorithm is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information. Encryption converts data to an unintelligible form called ciphertext; decrypting the ciphertext converts the data back into its original form, called plaintext. The AES algorithm is capable of using cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits.
