What it can do:
- Decodes records and most standard messages and extensions.
- Decryptes records and reassemples application data stream if a keylog is provided
and the cipher suite is supported.
- Supports most recommended and used ciphers and a bunch of older ones.
What it can't do:
- SSL v3 maybe supported, is similar to TLS 1.0, not tested.
- Decryption and renegotiation/cipher change.
- Record defragmentation not supported, seems rare over TCP.
- TLS 1.3
- SSL v2 but v2 compat header is supported.
- Some key exchange messages not decoded yet
Decryption code is heavly based on golang crypto/tls and zmap/zcrypto.
Will be base for decoding http2 and other TLS based on protocols.
Fixes#587
raw format was a hack to skip decoding to be able to get a binary using tobyte etc.
Now you can do fq -d bytes ... instead of fq -d raw 'tobytes | ...'
Make more sense to use a more general name when there is both info and xing
and possibly vbri in the future. Also both xing and info seems to have extension
fields
Remove some old tests that are not really needed anymore.
Split fat macho into own decoder macho_fat. This also fixes issue with section
offset etc not being correct as they are from the start of each embedded file.
Make all address and offset field be in hex.
Decode __cstring, __ustring and __cfstring sections.
Fix LC_ENCRYPTION_INFO_64 missing pading issue.
Skip ranging for __bss and __common as they dont have any data in the file.
Simplifed magic handling a bit and add symbols.
Simplified state struct field, had redudant struct.
json, yaml, toml, xml, html, csv are now normal formats and most of them also particiate
in probing (not html and csv).
Also fixes a bunch of bugs in to/fromxml, to/fromjq etc.
Rename s/interface{}/any/g
Preparation for using generics in decode API and native jq funcations etc
Remove some unused linter ignores as linter has been fixed
interp: Refactor format help and also include options
interp: Add -o name=@path to load file content as value (not documented yet, might change)
interp,decode: Expose decode out value as _out (might change)
interp: Refactor foramts.jq into format_{decode,func,include}.jq
interp: Refactor torepr into _format_func for generic format function overloading
interp: Refactor -o options parsing to be more generic and collect unknowns options to be used as format options
decode of decode alises
func for format overloaded functions
include for format specific jq functions (also _help, torepr etc)
flac_frame: Add bits_per_sample option
mp3: Add max_unique_header_config and max_sync_seek options
mp4: Add decode_samples and allow_truncate options
avc_au: Has length_size option
hevc_au: Has length_size option
aac_frame: Has object_typee option
doc: Rewrite format doc generation, less hack more jq
rtmp: check port based on tcp direction
dns,rtmp: refactor to use tcp and udp port match helpers
flow: add has start/end to tcp to know if stream has missing bytes
Refactor to use groups between network layers to make them less coupled and reusable:
link_frame (ethernet etc)
inet_packet (ipv4,ipv6 etc)
ip_packet (tcp packet (not stream), udp segment etc)
Rename data to payload as i think it makes more sense for network data
Basic support, can also do CER and DER but without any extra validation.
No schema support.
Redo format doc.md usage a bit, now format/<dir>/<format>.md instead.
