+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+A \fBBN_CTX\fR is a structure that holds \fBBIGNUM\fR temporary variables used by
+library functions. Since dynamic memory allocation to create \fBBIGNUM\fRs
+is rather expensive when used in conjunction with repeated subroutine
+calls, the \fBBN_CTX\fR structure is used.
+.PP
+\&\fBBN_CTX_new_ex()\fR allocates and initializes a \fBBN_CTX\fR structure for the given
+library context \fBctx\fR. The <ctx> value may be NULL in which case the default
+library context will be used. \fBBN_CTX_new()\fR is the same as \fBBN_CTX_new_ex()\fR except
+that the default library context is always used.
+.PP
+\&\fBBN_CTX_secure_new_ex()\fR allocates and initializes a \fBBN_CTX\fR structure
+but uses the secure heap (see \fBCRYPTO_secure_malloc\fR\|(3)) to hold the
+\&\fBBIGNUM\fRs for the given library context \fBctx\fR. The <ctx> value may be NULL in
+which case the default library context will be used. \fBBN_CTX_secure_new()\fR is the
+same as \fBBN_CTX_secure_new_ex()\fR except that the default library context is always
+used.
+.PP
+\&\fBBN_CTX_free()\fR frees the components of the \fBBN_CTX\fR and the structure itself.
+Since \fBBN_CTX_start()\fR is required in order to obtain \fBBIGNUM\fRs from the
+\&\fBBN_CTX\fR, in most cases \fBBN_CTX_end()\fR must be called before the \fBBN_CTX\fR may
+be freed by \fBBN_CTX_free()\fR.  If \fBc\fR is NULL, nothing is done.
+.PP
+A given \fBBN_CTX\fR must only be used by a single thread of execution.  No
+locking is performed, and the internal pool allocator will not properly handle
+multiple threads of execution.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBBN_CTX_new()\fR and \fBBN_CTX_secure_new()\fR return a pointer to the \fBBN_CTX\fR.
+If the allocation fails,
+they return \fBNULL\fR and sets an error code that can be obtained by
+\&\fBERR_get_error\fR\|(3).
+.PP
+\&\fBBN_CTX_free()\fR has no return values.
+.SH "REMOVED FUNCTIONALITY"
+.IX Header "REMOVED FUNCTIONALITY"
+.Vb 1
+\& void BN_CTX_init(BN_CTX *c);
+.Ve
+.PP
+\&\fBBN_CTX_init()\fR is no longer available as of OpenSSL 1.1.0. Applications should
+replace use of BN_CTX_init with BN_CTX_new instead:
+.PP
+.Vb 6
+\& BN_CTX *ctx;
+\& ctx = BN_CTX_new();
+\& if (!ctx)
+\&     /* error */
+\& ...
+\& BN_CTX_free(ctx);

+\&\fBBN_CTX_init()\fR was removed in OpenSSL 1.1.0.
