我有一个 php 文件,如下所示:
$encryption_encoded_key = 'c7e1wJFz+PBwQix80D1MbIwwOmOceZOzFGoidzDkF5g=';
function my_encrypt($data, $key) {
$encryption_key = base64_decode($key);
$iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-256-cfb'));
$encrypted = openssl_encrypt($data, 'aes-256-cfb', $encryption_key, 1, $iv);
// The $iv is just as important as the key for decrypting, so save it with encrypted data using a unique separator (::)
return base64_encode($encrypted . '::' . $iv);
}
function my_decrypt($data, $key) {
// Remove the base64 encoding from key
$encryption_key = base64_decode($key);
// To decrypt, split the encrypted data from IV - unique separator used was "::"
list($encrypted_data, $iv) = explode('::', base64_decode($data), 2);
return openssl_decrypt($encrypted_data, 'aes-256-cfb', $encryption_key, 1, $iv);
}
$data = 'USER_ID||NAME||EMAIL||MOBILE';
$data_encrypted = my_encrypt($data, $encryption_encoded_key);
echo $data_encrypted;
$data_decrypted = my_decrypt($data_encrypted, $encryption_encoded_key);
echo "Decrypted string: ". $data_decrypted;
这工作正常,并且能够使用加密密钥加密/解密,现在我还有一个 python 文件:
import hashlib
import base64
from Crypto.Cipher import AES
from Crypto import Random
encryption_encoded_key = 'c7e1wJFz+PBwQix80D1MbIwwOmOceZOzFGoidzDkF5g='
def my_encrypt(data, key):
#Remove the base64 encoding from key
encryption_key = base64.b64decode(key)
#Generate an initialization vector
bs = AES.block_size
iv = Random.new().read(bs)
cipher = AES.new(encryption_key, AES.MODE_CFB, iv)
#Encrypt the data using AES 256 encryption in CBC mode using our encryption key and initialization vector.
encrypted = cipher.encrypt(data)
#The iv is just as important as the key for decrypting, so save it with encrypted data using a unique separator (::)
return base64.b64encode(encrypted + '::' + iv)
def my_decrypt(data, key):
#Remove the base64 encoding from key
encryption_key = base64.b64decode(key)
#To decrypt, split the encrypted data from IV - unique separator used was "::"
encrypted_data, iv = base64.b64decode(data).split('::')
cipher = AES.new(encryption_key, AES.MODE_CFB, iv)
return cipher.decrypt(encrypted_data)
data = 'USER_ID||NAME||EMAIL||MOBILE'
print "Actual string: %s" %(data)
data_encrypted = my_encrypt(data, encryption_encoded_key)
print data_encrypted
data_decrypted = my_decrypt(data_encrypted, encryption_encoded_key)
print "Decrypted string: %s" %(data_decrypted)
当我尝试从 python 使用它时,这也工作得很好,它能够加密/解密输入字符串,
我想使用 php 文件加密并解密 python 中的输出,两者都应该使用 CFB 模式使用 AES 256 加密,我做错了什么?
