SQ(1)

NAME
sq toolbox packet - Low-level packet manipulation

SYNOPSIS
sq toolbox packet dump [OPTIONS] FILE
sq toolbox packet decrypt [OPTIONS] FILE
sq toolbox packet split [OPTIONS] FILE
sq toolbox packet join [OPTIONS] FILE

DESCRIPTION
Low-level packet manipulation.

An OpenPGP data stream consists of packets. These tools allow working with packet streams. They are mostly of interest to developers, but `sq toolbox packet dump` may be helpful to a wider audience both to provide valuable information in bug reports to OpenPGP-related software, and as a learning tool.

SUBCOMMANDS

  sq toolbox packet dump
Lists packets.

Creates a human-readable description of the packet sequence. Additionally, it can print cryptographic artifacts, and print the raw octet stream similar to hexdump(1), annotating specifically which bytes are parsed into OpenPGP values.

To inspect encrypted messages, either supply the session key, or see `sq decrypt` with the `--dump` flag, or `sq toolbox packet decrypt`.

  sq toolbox packet decrypt
Unwraps an encryption container.

Decrypts a message, dumping the content of the encryption container without further processing. The result is a valid OpenPGP message that can, among other things, be inspected using `sq toolbox packet dump`.

  sq toolbox packet split
Splits a message into packets.

Splitting a packet sequence into individual packets, then recombining them freely with `sq toolbox packet join` is a great way to experiment with OpenPGP data.

The converse operation is `sq toolbox packet join`.

  sq toolbox packet join
Joins packets split across files.

Splitting a packet sequence into individual packets, then recombining them freely with `sq toolbox packet join` is a great way to experiment with OpenPGP data.

The converse operation is `sq toolbox packet split`.

EXAMPLES

  sq toolbox packet dump

Prints the packets of a certificate

    sq toolbox packet dump juliet.pgp

Prints cryptographic artifacts of a certificate

    sq toolbox packet dump --mpis juliet.pgp

Prints a hexdump of a certificate

    sq toolbox packet dump --hex juliet.pgp

Prints the packets of an encrypted message

    sq toolbox packet dump --session-key AABBCC... ciphertext.pgp

  sq toolbox packet decrypt

Unwraps the encryption revealing the signed message

    sq toolbox packet decrypt --recipient-file juliet.pgp \
        ciphertext.pgp

  sq toolbox packet split

Split a certificate into individual packets

    sq toolbox packet split juliet.pgp

  sq toolbox packet join

Split a certificate into individual packets

    sq toolbox packet split juliet.pgp

Then join only a subset of these packets

    sq toolbox packet join juliet.pgp-[0-3]*
