They are distinct from SHA\-224 and SHA\-256 even though +their outputs are of the same size. +.SH NOTES +.IX Header "NOTES" +Developers should be aware of the negative performance implications of +calling these functions multiple times and should consider using +\&\fBEVP_MD_fetch\fR\|(3) with \fBEVP_MD\-SHA2\fR\|(7)instead. +See "Performance" in \fBcrypto\fR\|(7) for further information. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +These functions return a \fBEVP_MD\fR structure that contains the +implementation of the message digest.
