puttykeys 1.0.3

Library to convert Putty private keys to OpenSSH format

A module to convert SSH keys from the Putty format to the OpenSSH format. Supports RSA and ED25519 keys. Implements one method, ppkraw_to_openssh(ppk_text_contents[, password]) which decodes the supplied putty key if a password is provided, converts to OpenSSH format and returns it as a string. The returned output string is not encrypted or password protected.

Usage in python code:

import puttykeys
putty_key_contents = open("rsa_no_password.ppk","r").read()
print(puttykeys.ppkraw_to_openssh(putty_key_contents))

password_ppk_contents = open("rsa_with_password.ppk","r").read()
print(puttykeys.ppkraw_to_openssh(password_ppk_contents, "password"))

Usage via command line:

> python -m puttykeys rsa_no_password.ppk
