Again, this setting is disabled by default and is usually kept off. The Encrypt New Messages By Default option will tell the e-mail client to automatically encrypt the contents of the message if the recipient has a key in the PGP keyring. This option is usually disabled by default, as PGP/MIME is not recognized by every e-mail application. The option Use PGP/MIME When Sending E-Mail specifies whether e-mail is sent using PGP/MIME encryption.
In other words, if you trust me, you trust everyone I trust. If you trust that my digital certificate authenticates my identity, the Web of trust means you trust all the digital certificates that I trust. PGP uses a Web of trust model to authenticate digital certificates, instead of relying on a central certificate authority (CA). It can be used to encrypt emails, documents, or an entire disk drive. PGP provides the modern suite of cryptography: confidentiality, integrity, authentication, and nonrepudiation. Zimmerman agreed to stop publishing PGP to address the patent issue (though copies were freely available from other sources).
#BEST PGP EMAILER LICENSE#
Zimmerman had encouraged users to pay RSA for a license if they used the algorithm. RSA complained to Zimmerman for including the (then) patented RSA algorithm in PGP. The prosecutors dropped the case in 1996.
#BEST PGP EMAILER CODE#
Zimmerman was investigated for munitions export violations by the United States government after the PGP source code was posted to the Usenet bulletin board system in 1991. For the first time, an average computer user could easily leverage the power of asymmetric encryption, which allows strangers (including criminals) to securely communicate without pre-sharing a key. Phil Zimmerman created a controversy when he released PGP in 1991. Pretty Good Privacy (PGP) brought asymmetric encryption to the masses.
