The Java platform includes built-in providers for many of the most commonly used cryptographic algorithms, including the RSA, DSA, and ECDSA signature algorithms, the AES encryption algorithm, the SHA-2 message digest algorithms, and the Diffie-Hellman (DH) and Elliptic Curve Diffie-Hellman (ECDH...
DSA(Digital Signature Algorithm,数字签名) ECC(Elliptic Curves Cryptography,椭圆曲线密码编码学) 本篇内容简要介绍BASE64、MD5、SHA、HMAC几种方法。 MD5、SHA、HMAC这三种加密算法,可谓是非可逆加密,就是不可解密的加密方法。我们通常只把他们作为加密的基础。单纯的以上三种的加密并不可靠。
