RealCrypto 0.1.0

python version of rsa

Python 实现RSA、AES加解密

项目立意是为了解除python多数库只能使用公钥加密的限制。

示例

RSA加解密

from RealCrypto import Rsa


pyrsa = Rsa()

pub_key = """
-----BEGIN RSA PUBLIC KEY-----
xxxxxxxxxxxxxxxxxxxxxxxxxxxx
-----END RSA PUBLIC KEY-----
"""

data = "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"

ret = pyrsa.pub_decrypt(bytes.fromhex(data), pub_key)
print(ret)

ret = pyrsa.pub_encrypt("23342321",pub_key)
print(ret)

AES加解密

from RealCrypto import Aes,AesType

pyaes = Aes()

key = "1234657887654321"
iv = "1236547896325418"
plaintext = "just a test"
ret = pyaes.encrypt(plaintext,AesType.evp_aes_128_cbc, key,iv)
ret = pyaes.decrypt(ret,AesType.evp_aes_128_cbc, key,iv)
assert plaintext,ret.decode("utf-8")

Hash算法

teststr = "just a test"

# 字符串hash
ret = hash.md5(teststr)
print(ret.hex())

ret = hash.sha256(teststr)
print(ret.hex())


filepath = "test.txt"
# 文件hash
ret = hash.md5withfile(filepath)
print(ret.hex())

ret = hash.sha256withfile(filepath)
print(ret.hex())
