Of course, if the point of using the command line is to avoid writing sensitive data, it is important that the commands used are not stored in the history file.

This is a benefit because it lets the user review, edit and resubmit commands. WARNING: One of the benefits of using the command line is that commands are stored in RAM, and at the end of a session the command history is written to a history file.

The command being fed the string should look familiar GPG will encrypt the string to the public key associated with “Peter Loshin”, without the GPG software version information, as ASCII armored output. In this case, the output from the echo command is piped to another command, using the | character (vertical bar). The first part ( echo 'secret message for Peter') simply repeats the string “secret message for Peter” the echo command can be used also to list a file to screen.

$ echo 'secret message for Peter' | gpg -encrypt -armor -recipient 'Peter Loshin' -no-version This command is an example of entering a short message (“secret message for Peter”) at the command line: Sometimes it’s best to encrypt a quick message by typing text at the command line, and having GnuPG output ASCII armored text that can be cut and pasted into a message, bypassing the need to store sensitive data–encrypted or not–permanently on disk.

If such files are deleted, delete them securely or else they can be recovered almost as easily if they were not deleted at all. The existence of files containing encrypted data might be considered incriminating, depending on who finds those files leaving files with plaintext output from decrypted messages may (obviously) compromise that plaintext if an attacker has access to the system. Storing GnuPG content of any kind (that is, plain text to be encrypted, encrypted text to be decrypted, even public keys from co-respondents) on disk can result in the same kind of vulnerabilities associated with storing any sensitive data on disk.
