ossl\-removed\-api \- API that has been removed from OpenSSL
.SH SYNOPSIS
.IX Header "SYNOPSIS"
This page lists API that has been removed from OpenSSL, and when it was removed.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
This page documents a list of API that has been removed from
OpenSSL. Functions are not removed until they have been deprecated for
some time (Normally at least one major OpenSSL release, if not
more). This means that during at least one previous major release of
OpenSSL, deprecation warnings would have been emitted at compile time
when using this function, and the documentation would have contained
information on how to move away from the deprecated API.
.PP
Once a deprecated function is removed, The documentation for that
function will also be removed in order to keep the documentation
relevant to the current release. Normally, you should consult a
previous major release of OpenSSL where this function still existed,
and make changes to your code to no longer use the function as
documented in that release.
.PP
This includes consulting the \fBossl\-guide\-migration\fR\|(7) documentation.
