SSL_get1_builtin_sigalgs.3ossl - Man Page

get list of built-in signature algorithms

Synopsis

 #include <openssl/tls1.h>

 char *SSL_get1_builtin_sigalgs(OSSL_LIB_CTX *libctx);

Description

Return the colon-separated list of built-in and available TLS signature algorithms. The string returned must be freed by the user using OPENSSL_free(3).

Notes

The string may be empty (strlen==0) if none of the built-in TLS signature algorithms can be activated, e.g., if suitable providers are missing.

Return Values

NULL may be returned if no memory could be allocated. Otherwise, a newly allocated string is always returned but it may have strlen == 0.

History

This function was added in OpenSSL 3.4.
