The array B of length B +must consist of pairs of NIDs corresponding to digest and public key +algorithms. + +SSL_CTX_set1_sigalgs_list() and SSL_set1_sigalgs_list() set the supported +signature algorithms for B or B. The B parameter +must be a null terminated string consisting or a colon separated list of +public key algorithms and digests separated by B<+>. + +SSL_CTX_set1_client_sigalgs(), SSL_set1_client_sigalgs(), +SSL_CTX_set1_client_sigalgs_list() and SSL_set1_client_sigalgs_list() set +signature algorithms related to client authentication, otherwise they are +identical to SSL_CTX_set1_sigalgs(), SSL_set1_sigalgs(), +SSL_CTX_set1_sigalgs_list() and SSL_set1_sigalgs_list(). + +All these functions are implemented as macros. The signature algorithm +parameter (integer array or string) is not freed: the application should +free it, if necessary. + +=head1 NOTES + +If an application wishes to allow the setting of signature algorithms +as one of many user configurable options it should consider using the more +flexible SSL_CONF API instead. + +The signature algorithms set by a client are used directly in the supported +signature algorithm in the client hello message. + +The supported signature algorithms set by a server are not sent to the +client but are used to determine the set of shared signature algorithms +and (if server preferences are set with SSL_OP_CIPHER_SERVER_PREFERENCE) +their order. + +The client authentication signature algorithms set by a server are sent +in a certificate request message if client authentication is enabled, +otherwise they are unused. + +Similarly client authentication signature algorithms set by a client are +used to determined the set of client authentication shared signature +algorithms. + +Signature algorithms will neither be advertised nor used if the security level +prohibits them (for example SHA1 if the security level is 4 or more). + +Currently the NID_md5, NID_sha1, NID_sha224, NID_sha256, NID_sha384 and +NID_sha512 digest NIDs are supported and the public key algorithm NIDs +EVP_PKEY_RSA, EVP_PKEY_DSA and EVP_PKEY_EC. + +The short or long name values for digests can be used in a string (for +example "MD5", "SHA1", "SHA224", "SHA256", "SHA384", "SHA512") and +the public key algorithm strings "RSA", "DSA" or "ECDSA". + +The use of MD5 as a digest is strongly discouraged due to security weaknesses. + +=head1 EXAMPLES + +Set supported signature algorithms to SHA256 with ECDSA and SHA256 with RSA +using an array: + + const int slist[] = {NID_sha256, EVP_PKEY_EC, NID_sha256, EVP_PKEY_RSA}; + + SSL_CTX_set1_sigalgs(ctx, slist, 4); + +Set supported signature algorithms to SHA256 with ECDSA and SHA256 with RSA +using a string: + + SSL_CTX_set1_sigalgs_list(ctx, "ECDSA+SHA256:RSA+SHA256"); + +=head1 RETURN VALUES + +All these functions return 1 for success and 0 for failure. + +=head1 SEE ALSO + +L, L, +L + +=head1 COPYRIGHT + +Copyright 2015-2016 The OpenSSL Project Authors.
