that depends on what version of PGP you are using. Usually for command line you can type the comand followed by either /? or --help or possibly just type the command without any parameters.
let us know which version of pgp you have.
you will need the *private key* in order to decrypt. pgp files are encrypted using the public key and decrypted by using the private key.
Always remember that pgp files must always be encrypted with the *recipients* public key.
Its also possible that the encrypted PGP file that you have is only encrypted with a password and not with a key. PGP files that are encrypted only with a password are called conventionally encrypted.
I'm using the commandline utility version 6.5.8. I'm the recipient of the .pgp file and I have a public key .asc at hand. when I try to decrypt using the GUI I double click on the .pgp then it asks for a passphrase for my private key. When I enter passphrase then .pgp file is decrypted. How do I similute this identical process on the command line?
