   Posted by: admin    in Mẹo vặt của hiếu râu, python

pip3 install pgpy

[root@master-node pgp]# cat keygen.py

from pgpy.constants import PubKeyAlgorithm, KeyFlags, HashAlgorithm, SymmetricKeyAlgorithm, CompressionAlgorithm

import pgpy

key = pgpy.PGPKey.new(PubKeyAlgorithm.RSAEncryptOrSign, 4096)

uid = pgpy.PGPUID.new(’Harry’, comment=’Harrys test key’, email=’harry@——.com’)

key.add_uid(uid, usage={KeyFlags.Sign, KeyFlags.EncryptCommunications, KeyFlags.EncryptStorage},

hashes=[HashAlgorithm.SHA256, HashAlgorithm.SHA384, HashAlgorithm.SHA512, HashAlgorithm.SHA224],

ciphers=[SymmetricKeyAlgorithm.AES256, SymmetricKeyAlgorithm.AES192, SymmetricKeyAlgorithm.AES128],

compression=[CompressionAlgorithm.ZLIB, CompressionAlgorithm.BZ2, CompressionAlgorithm.ZIP, CompressionAlgorithm.Uncompressed])

print(key)

print(key.pubkey)

==================================
[root@master-node pgp]# cat encrypt.py
import sys
import pgpy
pubkey, _ = pgpy.PGPKey.from_file(”pgpkey.pub”)
message = pgpy.PGPMessage.new(sys.argv[1], file=True)
encrypted_message = pubkey.encrypt(message)
fo=sys.argv[2]
f2=open(fo,”w”)
f2.write(str(encrypted_message))
f2.close()
=====================================
[root@master-node pgp]# cat decrypt.py
import sys
import pgpy
key, _ = pgpy.PGPKey.from_file(”pgpkey”)
#f1=open(sys.argv[1],”rb”)
#message=f1.read()
#f1.close()
message = pgpy.PGPMessage.from_file(sys.argv[1])
decrypted_message = key.decrypt(message).message
fo=sys.argv[2]
f2=open(fo,”wb”)
f2.write(bytes(decrypted_message))
f2.close()
