# pyjsbn-rsa
Python RSA module compatible with [jsbn.js](http://www-cs-students.stanford.edu/%7Etjw/jsbn/).
## Installation
pyjsbn-rsa is available via PyPI
pip install pyjsbn-rsa
via setup.py
python setup.py install
## Basic Use
You can test module with [jsbn's RSA Encryption Demo](http://www-cs-students.stanford.edu/~tjw/jsbn/rsa.html)
>>from jsbn import RSAKey
>>rsa = RSAKey()
>>rsa.generate(1024,"10001")
>>hex(rsa.n)

Paste rsa.n to demo's *Modulus (hex)* and press encryt. (without "0x" and "L") And, get *Ciphertext (hex)* value
>>ctext="ceffa610eb7ec7fcbda60b2fdecf6d7cc65b7304ecb6e327056f15d763f1d079d376dbc801861a0ccb2731f836e75de0bb22350b3cd0d18eed216619b9e64a59dc06e15ef2531f0d3c176882444c5919dd751e9bcaefadff372d847b001a298751ebc69f9d310d92c217ab2fa433e3b3c7e8edf4744849560a317ef7f4ee7266"
>>rsa.decrypt(ctext)
'Hello World!'
## Methods
You can use main methods of rsa.js and rsa2.js
### setPublic
Set the public key fields N and e from hex strings.
>>rsa.setPublic(n,e)
### setPrivate
Set the private key fields N, e, and d from hex strings.
>>rsa.setPrivate(n,e,d)
### setPrivateEx
Set the private key fields N, e, d and CRT params from hex strings.
>>rsa.setPrivateEx(n,e,d,p,q,dp,dq,c)
### encrypt
Return the PKCS#1 RSA encryption of "text" as an even-length hex string. You should do ```setPublic```, ```setPrivate```, ```setPrivateEx``` or ```generate``` first. `text` must be ```unicode``` for Python 2 and ```str``` for Python 3.
>>rsa.encrypt(text)
### decrypt
Return the PKCS#1 RSA decryption of "ctext". "ctext" is an even-length hex string and the output is a plain string. You should do ```setPrivate```, ```setPrivateEx``` or ```generate``` first.
>>rsa.decrypt(ctext)
### generate
Generate a new random private key B bits long, using public expt E
>>rsa.generate(b,e)
