+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+The \fBEVP_PKEY_encrypt_init()\fR function initializes a public key algorithm
+context using key \fBpkey\fR for an encryption operation.
+.PP
+The \fBEVP_PKEY_encrypt_init_ex()\fR function initializes a public key algorithm
+context using key \fBpkey\fR for an encryption operation and sets the
+algorithm specific \fBparams\fR.
+.PP
+The \fBEVP_PKEY_encrypt()\fR function performs a public key encryption operation
+using \fBctx\fR. The data to be encrypted is specified using the \fBin\fR and
+\&\fBinlen\fR parameters. If \fBout\fR is \fBNULL\fR then the maximum size of the output
+buffer is written to the \fBoutlen\fR parameter. If \fBout\fR is not \fBNULL\fR then
+before the call the \fBoutlen\fR parameter should contain the length of the
+\&\fBout\fR buffer, if the call is successful the encrypted data is written to
+\&\fBout\fR and the amount of data written to \fBoutlen\fR.
+.SH NOTES
+.IX Header "NOTES"
+After the call to \fBEVP_PKEY_encrypt_init()\fR algorithm specific control
+operations can be performed to set any appropriate parameters for the
+operation.  These operations can be included in the \fBEVP_PKEY_encrypt_init_ex()\fR
+call.
+.PP
+The function \fBEVP_PKEY_encrypt()\fR can be called more than once on the same
+context if several operations are performed using the same parameters.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBEVP_PKEY_encrypt_init()\fR, \fBEVP_PKEY_encrypt_init_ex()\fR and \fBEVP_PKEY_encrypt()\fR
+return 1 for success and 0 or a negative value for failure. In particular a
+return value of \-2 indicates the operation is not supported by the public key
+algorithm.
+.SH EXAMPLES
+.IX Header "EXAMPLES"
+Encrypt data using OAEP (for RSA keys). See also \fBPEM_read_PUBKEY\fR\|(3) or
+\&\fBd2i_X509\fR\|(3) for means to load a public key. You may also simply
+set 'eng = NULL;' to start with the default OpenSSL RSA implementation:
