DESCRIPTION
gpg-zip is a convenience wrapper script from the GnuPG package that automates compressing files with gzip and encrypting or signing them with gpg in a single step. It produces a .gpgz output file combining compression and cryptographic protection, ideal for secure backups, email attachments, or archiving sensitive data.
The workflow pipes input files through gzip for compression, then gpg for encryption/signing (or reverse for decryption). For encryption, specify recipients with --recipient; use --symmetric for passphrase protection. Signing integrates with --sign or --sign-with. Multiple input files are concatenated before processing.
Decryption uses --decrypt or -d, automatically decompressing output. It passes most gpg options transparently, enhancing flexibility. While efficient for standard use, it's gzip-specific—no other compressors—and assumes GnuPG keys are configured. Widely used for its simplicity over manual piping.
CAVEATS
Always uses gzip externally; multiple files concatenated before processing. Passes unknown options to gpg, but decryption requires matching keys. Not suitable for non-gzip compression needs.
EXAMPLES
gpg-zip --encrypt --recipient alice files.txt → files.txt.gpgz
gpg-zip --symmetric --output secret.gpgz docs/
gpg-zip -d archive.gpgz → extracts decrypted files
DECRYPTION NOTE
Use gpg-zip -d file.gpgz; prompts for passphrase/key if needed, outputs to stdout or --output file.
HISTORY
Introduced in GnuPG 1.0 (circa 2001) as a user-friendly script; maintained in GnuPG 1.4/2.x for backward compatibility, though manual gpg | gzip preferred in modern workflows.
