Présentation : I've been developing an IPAM DCIM tool for work over the past several months more on that soon , and recently my focus has been on expanding it to store confidential data associated with network devices. Backup login credentials, TACACS RADIUS secrets, SNMP communities, and so on Short strings that need to be stored securely. Hashing ------- Storing a password or other small piece of sensitive data is different from merely authenticating against it. Most password storage mechanisms never actually store a user's actual password, but rather an irreversible hash of it. That is if you're doing it correctly, at least. For example, the Django Python framework which powers packetlife.net by default employs salted SHA256 hashes to authenticate user passwords. When a password is saved, a random salt is generated and concatenated with the plaintext password. A salt is used to prevent two identical passwords from producing the same hash. The SHA256 algorithm is then run against the whole thing to produce a fixed-length hash. Here's an example in Python using Django's built-in make_password function from django.contrib.auth.hashers import make_password make_password MyP ssw0rd u'pbkdf2_sha256 12000 x5E0yB2dh13m ablUOER8qn4CxjmHZlJrUUA1Cb9MeLXvfggTnG56QpM ' Continue reading No comments
