 =head1 DESCRIPTION
 
 SSL_CTX_load_verify_locations() specifies the locations for B<ctx>, at
 which CA certificates for verification purposes are located. The certificates
 available via B<CAfile> and B<CApath> are trusted.
 
+SSL_CTX_set_default_verify_paths() specifies that the default locations for
+which CA certificates are loaded should be used. There is one default directory
+and one default file.
+
+SSL_CTX_set_default_verify_dir() is similar to
+SSL_CTX_set_default_verify_paths() except that just the default directory is
+used.
+
+SSL_CTX_set_default_verify_file() is similar to
+SSL_CTX_set_default_verify_paths() except that just the default file is
+used.
+
 =head1 NOTES
 
 If B<CAfile> is not NULL, it points to a file of CA certificates in PEM
