Generating Your Encrypted Key in Cloud Backup

Rackspace Cloud Backup already encrypts your passphrase locally on your browser by using a JavaScript RSA library. Encryption happens before your passphrase is submitted over the web.

Rackspace will never know your unencrypted (or clear text) passphrase. Your passphrase is encrypted using public/private key pairs. This is the SSL web security standard for transmitting data over secure connections. Only your encrypted passphrase is sent to Rackspace. All communication between your computer and Rackspace servers for Cloud Backup is done over SSL. meaning that no one can intercept and read your messages. You can, however, encrypt your passphrase yourself using the public/private key for your system (and bypass Rackspace's client-side encryption library), by using the following method:

#!/usr/bin/env python
# - Create hex encryption key for API call to set encryption password.
# WARNING: This code might not work on some operating systems' flavors of python, 
# such as Mac OS-X
# # Example: thisismypassword public-key.pem import sys import binascii from Crypto.PublicKey import RSA from Crypto.Cipher import PKCS1_v1_5 def encrypt(secret, pemfile): public_key_path = pemfile print public_key_path public_key = None with open(public_key_path) as f: public_key = pkey = RSA.importKey(public_key) cipher = encrypted_password = cipher.encrypt(secret) hex_pass = binascii.hexlify(encrypted_password).decode() print hex_pass def syntax(): print 'syntax: rcbucrypt ' sys.exit(1) if (__name__ == "__main__"): if (len(sys.argv) == 1): syntax() secret = sys.argv[1] pemfile = sys.argv[2] encrypt(secret, pemfile)
