Per-browser TLS ClientHello fingerprint configuration.

Holds the raw TLS parameters needed to produce a JA3/JA4-identical ClientHello. Call to_tls_options to convert into hpx’s TlsOptions.

Fields

cipher_list: &'static str

Colon-separated cipher suite string for BoringSSL.

sigalgs_list: &'static str

Colon-separated signature algorithms string.

curves_list: &'static str

Colon-separated curves list.

extension_permutation: Vec<u16>

Extension type IDs in emission order.

cert_compression: Vec<CertCompression>

Certificate compression algorithms.

min_tls_version: &'static str

Minimum TLS version ("1.0" or "1.2").

ech_grease: bool

Enable ECH GREASE.

permute_extensions: bool

Enable extension permutation (Fisher-Yates shuffle).

no_session_ticket: bool

Disable session tickets (Safari iOS quirk).

grease_enabled: bool

GREASE enabled (disabled for Firefox).

ocsp_stapling: bool

Enable OCSP stapling.

signed_cert_timestamps: bool

Enable Signed Certificate Timestamps.

key_shares_limit: u8

Maximum key shares.

delegated_credentials: Option<&'static str>

Delegated credentials sigalg list (Firefox-only).

record_size_limit: Option<u16>

Record size limit (Firefox-only).

alps_use_new_codepoint: bool

Use new ALPS codepoint.

Implementations

impl DeviceFingerprint

pub fn to_tls_options(&self) -> TlsOptions

Convert to hpx’s TlsOptions.

Note: extension_permutation is not set here because hpx’s TlsOptionsBuilder uses boring’s ExtensionType which requires platform-specific conversion. Use extension_permutation to get the raw extension IDs.

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

Return the extension permutation, shuffled if this is a Chrome profile.

pub fn shuffled_chrome_permutation() -> Vec<u16>

Fisher-Yates shuffle of the Chrome extension permutation (for testing).

pub fn for_device(device_class: DeviceClass, browser_name: &str) -> Self

Return the correct fingerprint for a device class and browser name.

pub fn chrome_147() -> Self

Chrome 147 desktop/Android fingerprint.

pub fn safari_ios_18() -> Self

Safari iOS 18 fingerprint.

pub fn firefox_135() -> Self

Firefox 135 (NSS) fingerprint.

Trait Implementations

impl Clone for DeviceFingerprint

fn clone(&self) -> DeviceFingerprint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceFingerprint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
