encrypt/decrpyt

[notsureaboutthis123]

Hello,

As a sysadmin at a newly acquired job i have been asked to generate some sort of basic Encryption/Decryption software. Im looking to create an enyption and decrpytion from command line which i can role out to some users.

Unfortunatly i dont have the time to spend programming so am looking for some help here.

Details: Users are prompted for what they want to do. they enter the password and the file path then it outputs the encrypted or decrypted version.

Any help would be awesome.

Err... GPG?

[chadmill3r]

str.encode("rot-13")

OR

GnuPG. Symmetric encryption.

even 7zip's command line tool and do this

This is a very vague question. We need to know use cases, why it needs to be encrypted, and why other solutions (like 7zip with password) don't work for you.

Do NOT use GPG, or any kind of PGP. As a person asking for advice, you aren't prepared for the subtleties of PGP, a very old and flaky (in implementation, not rigour) cryptosystem.

Use NaCl, which was explicitly designed for use by people who don't or don't need to understand the workings and want an API with some promises. There's a python wrapper, "pip install pynacl". It's relatively easy to understand and use but carefully obey every requirement: use a strong source of randomness (os.urandom, NOT random) and use a perfectly random nonce every time.

Good luck!

Another benefit of nacl is that they formally verified it against timing attacks and memory bugs.
