我想在Python中使用相同的方法和配置任何人请帮助我。我是python新手,但仍然尝试了一些东西,但未能实现我想要的
import sys
import chilkat
crypt = chilkat.CkCrypt2()
# AES is also known as Rijndael.
crypt.put_CryptAlgorithm("aes")
# CipherMode may be "ctr", "cfb", "ecb" or "cbc"
crypt.put_CipherMode("ctr")
# KeyLength may be 128, 192, 256
crypt.put_KeyLength(256)
# Counter mode emits the exact number of bytes input, and therefore
# padding is not used. The PaddingScheme property does not apply with CTR mode.
# EncodingMode specifies the encoding of the output for
# encryption, and the input for decryption.
# It may be "hex", "url", "base64", "quoted-printable", or many other choices.
crypt.put_EncodingMode("hex")
# An initialization vector (nonce) is required if using CTR mode.
# The length of the IV is equal to the algorithm's block size.
# It is NOT equal to the length of the key.
ivHex = "000102030405060708090A0B0C0D0E0F"
crypt.SetEncodedIV(ivHex,"hex")
# The secret key must equal the size of the key. For
# 256-bit encryption, the binary secret key is 32 bytes.
# For 128-bit encryption, the binary secret key is 16 bytes.
keyHex = "000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F"
crypt.SetEncodedKey(keyHex,"hex")
# Encrypt a string...
# The input string is 44 ANSI characters (i.e. 44 bytes), so
# the output should be 48 bytes (a multiple of 16).
# Because the output is a hex string, it should
# be 96 characters long (2 chars per byte).
encStr = crypt.encryptStringENC("abc@test.com")
print('coming from here encryptStringENC',encStr)
decrypt = chilkat.CkCrypt2()
decrypt.put_CryptAlgorithm("aes")
decrypt.put_CipherMode("ctr")
decrypt.put_KeyLength(256)
decrypt.put_EncodingMode("hex")
decrypt.SetEncodedIV(ivHex,"hex")
decrypt.SetEncodedKey(keyHex,"hex")
decStr = decrypt.decryptStringENC(encStr)
print('decrypted data',decStr)
提前感谢。为了解决这个问题,我在NodeJS中创建了一个脚本。它将获取所有加密的用户id并返回解密的表单
var crypto = require('cryptojs');
function addDecryptedUserId(data) {
if (data.length) {
data.forEach(function (element) {
if (element.userId) {
element.decryptedUserId = crypto.decryptData(element.userId);
}
});
return data;
} else {
return [];
}
}
上述函数将获取所有元素,并向每个名为“decryptedUserId”的元素添加一个新属性,其中did
ivHex=“000102030405060708090A0B0C0D0E0F”和keyHex=“000102030405060708090A0C0D0F1011112131415161718191A1B1C1D1E1F”
coe from?它们必须与加密值匹配。当您在函数调用中嵌入函数调用时,例如secureKeyStore.decrypt(config.password)
可能看起来像是“leet/1337”,但调试变得非常困难,因为无法检查值以进行调试。不要这样做,使用中间临时变量。
