微信小程序 sha1 实现密码加密实例详解
在utils中的util.js 文件中增加 函数 实现 字符串转换为16进制加密后的字符串
function encodeUTF8(s) { var i, r = [], c, x; for (i = 0; i < s.length; i++) if ((c = s.charCodeAt(i)) < 0x80) r.push(c); else if (c < 0x800) r.push(0xC0 + (c 6 & 0x1F), 0x80 + (c & 0x3F)); else { if ((x = c ^ 0xD800) 10 == 0) //对四字节UTF-16转换为Unicode c = (x << 10) + (s.charCodeAt(++i) ^ 0xDC00) + 0x10000, r.push(0xF0 + (c 18 & 0x7), 0x80 + (c 12 & 0x3F)); else r.push(0xE0 + (c 12 & 0xF)); r.push(0x80 + (c 6 & 0x3F), 0x80 + (c & 0x3F)); }; return r; }; // 字符串加密成 hex 字符串 function sha1(s) { var data = new Uint8Array(encodeUTF8(s)) var i, j, t; var l = ((data.length + 8) > 6 << 4) + 16, s = new Uint8Array(l << 2); s.set(new Uint8Array(data.buffer)), s = new Uint32Array(s.buffer); for (t = new DataView(s.buffer), i = 0; i < l; i++)s[i] = t.getUint32(i << 2); s[data.length 2] |= 0x80 << (24 - (data.length & 3) * 8); s[l - 1] = data.length << 3; var w = [], f = [ function () { return m[1] & m[2] | ~m[1] & m[3]; }, function () { return m[1] ^ m[2] ^ m[3]; }, function () { return m[1] & m[2] | m[1] & m[3] | m[2] & m[3]; }, function () { return m[1] ^ m[2] ^ m[3]; } ], rol = function (n, c) { return n << c | n > (32 - c); }, k = [1518500249, 1859775393, -1894007588, -899497514], m = [1732584193, -271733879, null, null, -1009589776]; m[2] = ~m[0], m[3] = ~m[1]; for (i = 0; i < s.length; i += 16) { var o = m.slice(0); for (j = 0; j < 80; j++) w[j] = j < 16 "0" : "") + e.toString(16); }).join(""); return hex; };
导出函数
module.exports = { formatTime: formatTime, sha1:sha1 }
这样就可以在其他页面中调用了
var util = require('../../utils/util.js') util.sha1("123456")
以 密码为 123456 作为示例,在线加密结果
小程序中调用结果
加密结果是相同的
