L. M. Barreto. This implementation is only available with the legacy provider. .IP \fBEVP_whirlpool()\fR 4 .IX Item "EVP_whirlpool()" The WHIRLPOOL algorithm that produces a message digest of 512\-bits from a given input. .SH NOTES .IX Header "NOTES" Developers should be aware of the negative performance implications of calling this function multiple times and should consider using \&\fBEVP_MD_fetch\fR\|(3) with \fBEVP_MD\-WHIRLPOOL\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. See \fBEVP_MD_meth_new\fR\|(3) for details of the \fBEVP_MD\fR structure. .SH "CONFORMING TO" .IX Header "CONFORMING TO" ISO/IEC 10118\-3:2004. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBevp\fR\|(7), \&\fBprovider\fR\|(7), \&\fBEVP_DigestInit\fR\|(3) .SH COPYRIGHT .IX Header "COPYRIGHT" Copyright 2017\-2023 The OpenSSL Project Authors.
