高级加密标准(英语:Advanced Encryption Standard,缩写:AES),又称Rijndael加密法,是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES,已经被多方分析且广为全世界所使用。经过五年的甄选流程,高级加密标准由美国国家标准与技术研究院(NIST)于2001年11月26日发布于FIPS PUB 197,并在2002年5月26日成为有效的标准。现在,高级加密标准已然成为对称密钥加密中最流行的算法之一。
aes-192密钥的长度为24字节,aes-256密钥的长度为32字节,aes-128密码的长度为16字节。aes-ccm需要key,nonce,adata,另外aes-ccm不需要填充。
Counter with CBC-MAC (CCM)
