asp实现的sha1加密解密代码(和C#兼容)

这篇文章主要介绍了asp实现的sha1加密解密代码,可以和ASP.NET(C#)相互兼容,需要的朋友可以参考下
在百度找的几个asp sha1(vbs写的)加密结果和asp.的sha1加密结果不一样,asp. sha1加密完后是40位,网上找的asp sha1加密是64位,还以为asp.做了截取(如网上的asp的md5机密和asp.位数不一样,是做了截取的问题),asp的64位加密结果并没有包含asp.的40位结果,看来找到的版本和asp.的加密算法不一样。
还是靠翻墙用google找到了一个js版本的sha1加密代码结合asp使用后结果和asp.的sha1加密一模一样。。看来技术类的文字用度娘还是搞不过谷歌啊。。随便fuck下中国的防火墙。。谷歌也给封了。
asp sha1加密源代码如下,和asp.的sha1加密结果一致:
代码如下:

Configurable variables. You may need to tweak these to be patible with
the server-side, but the defaults work in most cases.
/
var hexcase = 0; / hex output format. 0 - lowercase; 1 - uppercase /
var b64pad = "="; / base-64 pad character. "=" for strict RFC pliance /
var chrsz = 8; / bits per input character. 8 - ASCII; 16 - Unicode /
/
These are the functions you'll usually want to call
They take string arguments and return either hex or base-64 encoded strings
/
function hex_sha1(s){return binb2hex(core_sha1(str2binb(s),s.length chrsz));}
function b64_sha1(s){return binb2b64(core_sha1(str2binb(s),s.length chrsz));}
function str_sha1(s){return binb2str(core_sha1(str2binb(s),s.length chrsz));}
function hex_hmac_sha1(key, data){ return binb2hex(core_hmac_sha1(key, data));}
function b64_hmac_sha1(key, data){ return binb2b64(core_hmac_sha1(key, data));}
function str_hmac_sha1(key, data){ return binb2str(core_hmac_sha1(key, data));}

Perform a simple self-test to see if the VM is working
/
function sha1_vm_test()
{
return hex_sha1("abc") == "a9993e364706816aba3e25717850c26c9cd0d89d";
}
/
Calculate the SHA-1 of an array of big-endian words, and a bit length
/
function core_sha1(x, len)
{
/ append padding /
x[len >> 5] |= 0x80 << (24 - len % 32);
x[((len + 64 >> 9) << 4) + 15] = len;
var w = Array(80);
var a = 1732584193;
var b = -271733879;
var c = -1732584194;
var d = 271733878;
var e = -1009589776;
for(var i = 0; i < x.length; i += 16)
{
var olda = a;
var oldb = b;
var oldc = c;
var oldd = d;
var olde = e;
for(var j = 0; j < 80; j++)
{
if(j < 16) w[j] = x[i + j];
else w[j] = rol(w[j-3] ^ w[j-8] ^ w[j-14] ^ w[j-16], 1);
var t = safe_add(safe_add(rol(a, 5), sha1_ft(j, b, c, d)),
safe_add(safe_add(e, w[j]), sha1_kt(j)));

/
Perform the appropriate triplet bination function for the current
iteration
/
function sha1_ft(t, b, c, d)
{
if(t < 20) return (b & c) | ((~b) & d);
if(t < 40) return b ^ c ^ d;
if(t < 60) return (b & c) | (b & d) | (c & d);
return b ^ c ^ d;
}

Determine the appropriate additive constant for the current iteration
/
function sha1_kt(t)
{
return (t < 20) ? 1518500249 : (t < 40) ? 1859775393 :
(t < 60) ? -1894007588 : -899497514;
}
/
Calculate the HMAC-SHA1 of a key and some data
/
function core_hmac_sha1(key, data)
{
var bkey = str2binb(key);
if(bkey.length > 16) bkey = core_sha1(bkey, key.length chrsz);
var ipad = Array(16), opad = Array(16);
for(var i = 0; i < 16; i++)

var hash = core_sha1(ipad.concat(str2binb(data)), 512 + data.length chrsz);
return core_sha1(opad.concat(hash), 512 + 160);
}
/
Add integers, wrapping at 2^32. This uses 16-bit operations internally
to work around bugs in some JS interpreters.
/
function safe_add(x, y)
{
var lsw = (x & 0xFFFF) + (y & 0xFFFF);
var msw = (x >> 16) + (y >> 16) + (lsw >> 16);
return (msw << 16) | (lsw & 0xFFFF);
}
/
Bitwise rotate a 32-bit number to the left.
/
function rol(num, t)
{
return (num << t) | (num >>> (32 - t));
}
/
Convert an 8-bit or 16-bit string to an array of big-endian words
In 8-bit function, characters >255 have their hi-byte silently ignored.
/
function str2binb(str)
{
var bin = Array();
var mask = (1 << chrsz) - 1;
for(var i = 0; i < str.length chrsz; i += chrsz)
bin[i>>5] |= (str.charCodeAt(i / chrsz) & mask) << (32 - chrsz - i%32);
return bin;
}
/
Convert an array of big-endian words to a string
/
function binb2str(bin)
{
var str = "";
var mask = (1 << chrsz) - 1;
for(var i = 0; i < bin.length 32; i += chrsz)
str += String.fromCharCode((bin[i>>5] >>> (32 - chrsz - i%32)) & mask);

hex_tab.charAt((binarray[i>>2] >> ((3 - i%4)8 )) & 0xF);

for(var j = 0; j < 4; j++)
{
if(i 8 + j 6 > binarray.length 32) str += b64pad;
