Pretty Good Privacy was developed by Phil Zimmermann. PGP is cross-platform data encryption and protection software that uses public and private keys for encryption, decryption, and digital signatures. A BEXPK file contains a public key extracted from a PGP key ring in binary form.
The file is a key data file rather than an encrypted document. PGP can use the extracted key when it is imported into a key ring or used in another PGP key-management operation.
Open the file with the Pretty Good Privacy software that created it, using PGP's key-management or key-import function. A BEXPK file is not intended to be read as ordinary text.
PGP for Microsoft Windows is the relevant software for this record. Compatibility with other PGP implementations may depend on their support for this binary key format.
A BEXPK file normally does not need conventional file conversion. To use the key in another PGP environment, import it into a compatible PGP key ring and export the public key in a format supported by that environment.
