How can I decrypt messages I've encrypted to others?

The comp.security.pgp FAQ
With conventional encryption, you can read the message by running PGP on the encrypted file and giving the pass phrase you used to encrypt. With the PGP 5.x and higher versions, it is the default setting to also encrypt to the default key. You can change this under PGP options / General / Always encrypt to default key. For PGP 2.x there is an undocumented setting, EncryptToSelf, which you can set in your config.

Cannot decrypt a file which was encrypted with CCrryyppttoo. Why?

FAQ
This FAQ assumes that you know your password and typed it correctly! The most likely cause for this problem is that you opened the encrypted file with Pocket Word or Pocket Excel. Never do this! Opening and closing an encrypted file will cause Pocket Word or Pocket Excel that the file will be saved (converted) even you haven't changed the file. If you accidentally opened an encrypted file do a soft-reset in order to avoid that the file will be saved (destroyed).

Often, encrypted & encrypted/signed messages are smaller than the original! Why?

PGP DH vs. RSA FAQ
Before encryption, messages are compressed using a standard compression algorithm [RFC1951]. Compressing data prior to encryption helps remove redundancy from the plaintext. Redundancy in the plaintext may aid cryptanalysis [BW94], [Sch96a], [MOV96], [Pfl97], [Bau97]. Interesting question! Actually, this is two separate questions as DNA and Quantum computing affect the security of PGP in different ways. First, Quantum Computers (QC).

How can I make sure my messages are being encrypted? Can I test the system?

Secure Email at The University of Kansas Medical Center
We encourage you to familiarize yourself with the system by sending secure messages to your home e-mail address or business associates that you would like to communicate with securely.

Why does it take so long to encrypt/decrypt messages?

The comp.security.pgp FAQ
This problem can arise when you have placed the entire public key ring from one of the servers into your local pubring.pgp file. PGP may have to search through several thousand keys to find the one that it is after. If you need to have these large keyrings (e.g. because you cannot count on being able to contact the keyservers to look up new keys), the solution to this dilemma is to maintain 2 public key rings (See How do I create a secondary key file?). The first ring, the normal pubring.

d. How to verify signed/encrypted messages in my e-mail applications?

If a digital signature can be verified, you can be sure about the sender's identity, and that the e-mail has not been tampered with during transmission.
