I think I may be misunderstanding the question somewhat -- why would PGP need an encryption passoword when _sending_ mail? &nbsp;When sending, you'll be encrypting with the recipient's public key, which should not be password protected (after all, there's no need to; it's a public key.)<br />
<br />
Also, what OS is this under?<br />

Is there any emailing encryption program that can be used to encrypt a file automatically from a program that does not require interaction with it?<br />
<br />
Tried using PGP (Pretty Good Privacy) but it requires you to enter the encryption password at the command prompt before the file could be encrypted. &nbsp;The program I'm trying to encrypt a file with PGP is a C CGI script before which the file is e-mailed.<br />
<br />
I will be grateful if there is a way round this, such as an encryption program you can pass the details as parameters to it before it is e-mailed!

File encryption

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
