tlsFingerprint() function

Computes a stable fingerprint of a TLS configuration, used to keep connections that differ in their transport security out of the same connection pool slot.

Two configurations that are equal by value share a fingerprint, so pooling still works across independently built option literals. Any difference in the trust anchors, the client certificate, the verification callbacks or the expected server name yields a different one.

Signature:

export declare function tlsFingerprint(tls: boolean | TlsOptions): string;

Parameters

Returns:

string

a hex digest identifying the configuration
