Overview ¶
Package fsid decodes an FSID (the JA4-inspired fingerprint id produced by fpscanner's generateFingerprintScannerId) back into a fingerprint object.
Only the fields the FSID actually encodes can be recovered: bitmasks, screen geometry, cpu/memory, language and timezone. Everything else was folded into truncated hashes and is gone; those fields are simply left out of the object.
Stdlib only on purpose: no crowdsec imports, so it stays usable from anywhere (cscli, tests, standalone tooling).

Width, Height int
CPUCount int
Memory int
Device map[string]bool
Features map[string]bool
Extensions map[string]bool

// Hashes of the signals the FSID does not carry in clear.
Hashes map[string]string
// Sections kept verbatim, handy when a section fails to match.
Sections map[string]string
Warnings []string
}
func Parse ¶
Parse decodes an FSID string. Sections that fail to decode are reported in Warnings rather than as an error: a partially readable FSID is still useful.
func (*FSID) Fingerprint ¶
Fingerprint rebuilds the JSON wire shape consumed by challenge.FingerprintData, with only the fields the FSID encodes.
func (*FSID) WriteHuman ¶
WriteHuman renders a readable summary of what the FSID carries.
