NAME

       SSL_get1_builtin_sigalgs - 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.
