This handly little application simplifies the task of encrypting and decrypting data.
The examples below demonstrate basic usage of the application.
To generate a new pre-shared key and encrypt a file with it:
clicrypt encrypt -c -k key -i plain.txt -o cipher.txt
Because clicrypt uses STDIN and STDOUT by default, the above command could also be written as:
clicrypt encrypt -c -k key < plain.txt > cipher.txt
To use an existing key instead of generating a new one, omit the -c flag.
To decrypt a file:
clicrypt decrypt -k key -i cipher.txt -o plain.txt
Once again, clicrypt uses STDIN and STDOUT by default, so the above command could also be written as:
clicrypt decrypt -k key < cipher.txt > plain.txt
clicrypt is designed to integrate easily with pipelines. For example, to compress and encrypt an entire directory, you could create a pipeline with tar:
tar czf - somedir | clicrypt encrypt -c -k key > encrypted.tar.gz
Decrypting and decompressing the directory could then be done with:
clicrypt decrypt -k key < encrypted.tar.gz | tar xzf -
