Encoding with base64

echo "Hello world" | base64
Also works with files: cat file Hello world base64 file SGVsbG8gd29ybGQK To decrypt use the -d option: echo SGVsbG8gd29ybGQK | base64 -d Hello world
Sample Output
SGVsbG8gd29ybGQK

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

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

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, this is encoding, not encryption. Yes, you`re right. I changed the title from "encryption" into "encoding".

Do not add a line break in your codded string. Use the -n echo's option: echo -n "Hello world" | base64
