cn.ponfee.commons.jce.digest.HmacUtils

public final class HmacUtils
extends Object

HMAC的一个典型应用是用在“质询/响应”（Challenge/Response）身份认证中 Hmac算法封装，计算“text”的HMAC： if (length(K) > blocksize) { K = H(K) // keys longer than blocksize are shortened } else if (length(key) < blocksize) { K += [0x00 * (blocksize - length(K))] // keys shorter than blocksize are zero-padded } opad = [0x5c * B] XOR K ipad = [0x36 * B] XOR K hash = H(opad + H(ipad + text)) 其中：H为散列函数，K为密钥，text为数据， B表示数据块的字长（the blocksize is that of the underlying hash function）
