To decrypt: ~$ echo -n 'jA0EAwMCPdknsznAww5gySL1/quqhXg6QgQkIz5abzGP5EZgTbXCFU+y6dP8ySWovytc' | base64 --decode | gpg --decrypt gpg: CAST5 encrypted data Enter passphrase: secret gpg: encrypted with 1 passphrase HelloWorld!

What Others Think

You can add --passphrase bar to complete the process in one pass without further intervention (and even do the decrypt through a batch file) YOU SHOULD NOT SAVE THE PASSWORD IN THE BATCH FILE (due to security concerns) BUT you can create a command line and submit it through another program by storing the passphrase separately

Besides, you can also store the password in a file and tell gpg to use a particular file descriptor to read it from. Then shred-u password-file when done. Also, consider the short forms of the command line switches above ;)
