pypinksign 0.1.1

Basic NPKI module.

Small python code for K-PKI certificates. 공인인증서를 다루는 파이선 코드입니다.

Support method

• Load personal purpose of NPKI a.k.a “공인인증서“

• Encrypt, Decrypt, Sign, Verify (part of Public-key cryptography)

• PKCS#7 sign, envelop

Usage example

import pypinksign
p = pypinksign.PinkSign()
p.load_pubkey(pubkey_path="/path/signCert.der")
p.load_prikey(prikey_path="/path/signPri.key", prikey_password="my-0wn-S3cret")
sign = p.sign('1')
verify = p.verify(sign, '1')  # True

or

import pypinksign

# choose_cert function automatically fetch path for certificates
# and load certificate which match DN and passpharase for Private Key
p = pypinksign.choose_cert(dn="홍길순", pw="i-am-h0ng")
sign = p.sign('1')
verify = p.verify(sign, '1')  # True
envelop = p.envelop_with_sign_msg('message')  # Envelop with K-PKI

Requirement & Dependency

• Python 2.7 (Probably works with python 3 and above, but not tested)

• PyCrypto for Crypto.PublicKey

• python-pkcs1 for pkcs1

• PyASN1 for pyasn1

• cryptography for cryptography.hazmat

• bitarray 0.8.1 for bitarray.bitarray

Installation

The easiest way to get skeleton is if you have setuptools / distribute or pip installed

easy_install pypinksign

or

pip install pypinksign
