# 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.
