What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

You can sign-in using OpenID credentials, or register a traditional username and password.

First-time OpenID users will be automatically assigned a username which can be changed after signing in.

UpGuard checks and validates configurations for every major OS, network device, and cloud provider.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Encoding with base64

Also works with files:

cat file

Hello world

base64 file


To decrypt use the -d option:

echo SGVsbG8gd29ybGQK | base64 -d

Hello world

What others think

Encryption is not the word I would use. Because what you are doing is not by any means creating a difficult-to-read version, since anybody has the tool to "decrypt" it.

I would rather use the word "obfuscation", and I'm not even so sure of that.

It's not encryption. It's hashing. Use gpg for encryption, or some other tool like truecrypt. My fav algo is rijndael

Comment by linuxrawkstar 468 weeks and 5 days ago

Base64 is not hashing either. it is simply character translation, encoding 8 bit characters into 6 bits. Useful for stuff that cannot handle full ASCII such as email. Use something like md5 for a true hash.

it's called coding. Not encryption

Comment by oernii 468 weeks and 4 days ago

Yes, this is encoding, not encryption. The benefit of base64 encoding, though, is that any arbitrary binary stream may be base64-encoded. (ASCII has nothing to do with it. In fact, to be precise, ASCII is a 7-bit encoding scheme. Anybody remember parity bits?)

Encryption method are not necessarily hard to break. base64 is an encryption method as it turns plaintext into something that you can only read if you have special knowledge. It is not the worst method either; a Cesar cipher like rot13 maps identical characters in the plaintext to identical characters in the ciphertext, base64 does not.

Yes, you`re right.

I changed the title from "encryption" into "encoding".

Comment by P17 467 weeks and 3 days ago

Do not add a line break in your codded string. Use the -n echo's option:

echo -n "Hello world" | base64
