To decrypt my password file I would use this line in my "auto-type" script: store="$ (gpg -q --batch --passphrase `dmenu -P` -d /path/to/file)" (The -P option for dmenu is added with a patch. Use a *good* password for your user account and a *good* passphrase to protect your secret key. Then line to decrypt copied from terminal of my MAC and tested works, w/ no prompt: gpg --batch --passphrase MyPassphrase -o test.tt7 -d CE.txt.gpg NOTE that: -d is the same as --decrypt and-o the same as --output And the value of the passphrase is the actual value I used in my test to decrypt the above and not the variable. The functions crypt() and gen_salt() are specifically designed for hashing passwords.crypt() does the hashing and gen_salt() prepares algorithm parameters for it. 0. gpg --symmetric --cipher-algo AES256 example.txt Using gpg and a symmetric key to encrypt. Step 2: Select the default RSA and RSA key type. For newer versions (v2.1+), disable password caching for the agent by creating ~/.gnupg/gpg-agent.conf and adding the following lines: --symmetric -c Encrypt with a symmetric cipher using a passphrase. A passphrase should be a single line of text, a trailing linefeed will be stripped. You may also add a comment if you want. The algorithms in crypt() differ from usual hashing algorithms like MD5 or SHA1 in the following respects:. (With gpg --debug help showing available choices to give after --debug.) I am trying to decrypt a gpg file, but am continually getting the following error: gpg: decryption failed: Bad session key. Step 4: Enter how long the key should last. I think that a quite secure method to pass the password to the command line is this: gpg --passphrase-file <(echo password) --batch --output outfile -c file What this will do is to spawn the "echo" command and pass a file descriptor as a path name to gpg (e.g. User has to import your public key. Step 2: Select the default RSA and RSA key type. gpg -e -r journalists filename.txt. The private key, which is protected by a passphrase, is handled by gpg-agent. The file is called Raven.txt. TOMB. Then, hit Enter to generate the files unique password. Decrypt the text: gpg --decrypt file.txt. Step 3: Enter 2048 as the default keysize for the encryption key. Whitch commands do I have to execute in Windows Command Line to sign a file without pinentry dialog? To sign a plaintext file with your secret key: gpg -s textfile. The file is called Raven.txt. root@user:~/gpg# cat secret.txt. Caution: don't forget your passphrase (password), there is no way to recover data with out the passphrase.
