JS前端加密算法示例

function decryptByDES(ciphertext, key) {
    var keyHex = CryptoJS.enc.Utf8.parse(key);
    var decrypted = CryptoJS.DES.decrypt({
    ciphertext: CryptoJS.enc.Base64.parse(ciphertext)
    }, keyHex, {
    mode: CryptoJS.mode.ECB,
    padding: CryptoJS.pad.Pkcs7
    });
    return decrypted.toString(CryptoJS.enc.Utf8);
}

$.get("http://127.0.0.1/image/image.data",function(data){
    var result = decryptByDES(data,'123');
    var image = "data:image/jpeg;base64,"+result;
    $('#show').attr("src", image);
