why do you want to change it?<br />
<br />
I don't think you can use any other 3des capable tool to decrypt pgp messages even if they are encrypted with 3des.<br />
<br />
If your partners don't want to pay for pgp you can still take the trial desktop edition, after the trial period it converts to the free version (with reduced function set) or you use gpg, a free opensource counterpart.<br />

I encrypted a file using the command line tool using the user's public key and signed it. But they could not decrypt it saying it was using the cipher IDEA. And asked me to change it to 3DES, blowfish, etc.<br />
Thanks

Yes I already tried that. Did not work.<br />

Hi,<br />
<br />
I am using PGP command line 6.5.8 to encrypt files. It works fine, but it uses IDEA cipher. How can i change it to some other like 3DES, Blowfish, etc?<br />
Thanks

How to change the cipher used for encryption?

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.

Security

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.
