Implementations

impl TlsFingerprint

pub fn firefox() -> TlsFingerprint

pub fn chrome() -> TlsFingerprint

pub fn chrome_120() -> TlsFingerprint

Chrome 120+ (Dec 2023) fingerprint

pub fn chrome_latest() -> TlsFingerprint

Chrome 130+ (Oct 2024+) latest fingerprint with updated extensions

pub fn compute_ja3(&self) -> String

pub fn compute_ja4(&self) -> String

JA4 fingerprint: <tls_version><num_suites><num_exts><alpn_hash> where alpn_hash is first 12 chars of SHA256 of sorted ALPN values

pub fn alpn_strings(&self) -> Vec<&str>

pub fn is_tls13_suite(&self, suite: u16) -> bool

pub fn tls13_suites(&self) -> Vec<u16>

pub fn tls12_suites(&self) -> Vec<u16>

pub fn tls12_cipher_list_string(&self) -> String

Convert TLS 1.2 cipher suite IDs to BoringSSL OpenSSL name string (colon-separated, e.g. “ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256”)

DHE suites are dropped: BoringSSL has no DHE_RSA implementation, so they can never be offered (see cipher_suite_boringssl_supported).

pub fn tls13_cipher_suites_string(&self) -> String

Convert TLS 1.3 cipher suite IDs to BoringSSL name string (colon-separated, e.g. “TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384”)

pub fn curves_list_string(&self) -> String

Convert supported group IDs to BoringSSL curves list string (colon-separated, e.g. “X25519:P-256:P-384”)

FFDHE groups are dropped: SSL_(CTX_)set1_groups_list fails the WHOLE call on any unrecognized name and BoringSSL implements no FFDHE group — an unfiltered Firefox list would silently discard the entire groups fingerprint (see group_boringssl_supported).

pub fn sigalgs_list_string(&self) -> String

Convert signature algorithm IDs to BoringSSL sigalgs list string (colon-separated, e.g. “ecdsa_secp256r1_sha256:rsa_pss_rsae_sha256”)

Trait Implementations

impl Clone for TlsFingerprint
