Does the recipient of files encrypted with PGP Command Line also require a copy of PGP Command Line?
Because PGP Command Line uses OpenPGP-compliant message formatting, recipients of files encrypted or signed using PGP Command Line require software capable of handling OpenPGP messages, such as PGP Command Line, PGP® Desktop, or PGP Universal. PGP Command Line also supports creation of Self-Decrypting Archives (SDAs), compressed and encrypted archives packaged as executables that require only a passphrase to decrypt. Organizations can use SDAs to securely transfer data to recipients who do not have OpenPGP-compatible software installed. PGP Command Line for mainframe operating systems creates SDA executables for server platforms supported by PGP Command Line. Please refer to PGP Command Line for server platforms for more information on supported platforms.
