Functions

get_whole_number(msg, idx, numlen)
extracts a "whole number" field of length numlen from msg at index idx returns (<whole number>, new_idx) where the whole number is a long integer and new_idx is the index of the next element in the message

source code

get_whole_int(msg, idx, numlen)
same as get_whole_number but returns the number as an int for convenience

source code

pack_long(l)
returns big-endian representation of unsigned long integer

source code

pack_mpi(l)
returns the PGP Multi-Precision Integer representation of unsigned long integer

source code

get_sig_subpak_len(msg, idx)
extracts a signature subpacket length field returns (subpak_len, new_idx)

source code

get_n_mpi(msg, idx)
extracts a multi-precision integer field from the message msg at index idx returns (n, <mpi>, new_idx) where the mpi is a long integer and new_idx is the index of the next element in the message and n is the number of bits of precision in <mpi>

source code

get_mpi(msg, idx)
extracts a multi-precision integer field from the message msg at index idx returns (<mpi>, new_idx) where the mpi is a long integer and new_idx is the index of the next element in the message

source code

str_to_hex(s)

source code

duration_to_str(s)

source code

map_to_str(m, vals)

source code

get_ctb(msg, idx)
extracts a the "cypher type bit" information from message msg at index idx returns (type, len, new_idx) where type is the enumerated type of the packet, len is the length of the packet, and new_idx is the index of the next element in the message

source code

crc24(msg)

source code

decode(msg)

source code

decode_msg(msg)
decode_msg(msg) ==> list of OpenPGP "packet" objects Takes an ascii-armored PGP block and returns a list of objects each of which corresponds to a PGP "packets".

[hide private]

decode_msg(msg)

source code

decode_msg(msg) ==> list of OpenPGP "packet" objects Takes an ascii-armored PGP block and returns a list of objects each of which corresponds to a PGP "packets".

A PGP message is a series of packets. You need to understand how packets are to be combined together in order to know what to do with them. For example a PGP "certificate" includes a public key, user id(s), and signature.
