# sasl_encodev - Encode data for transport to authenticated host

## Synopsis

    #include <sasl/sasl.h>

    int sasl_encode(sasl_conn_t *conn,
                    const char * input,
                    unsigned inputlen,
                    const char ** output,
                    unsigned * outputlen);

    int sasl_encodev(sasl_conn_t *conn,
                    const struct iovec * invec,
                    unsigned numiov,
                    const char ** output,
                    unsigned * outputlen);

## Description

sasl_encode encodes data to be sent to be sent to a remote host who we’ve had a successful authentication session with. If there is a negotiated security the data in signed/encrypted and the output should be sent without modification to the remote host. If there is no security layer the output is identical to the input.

sasl_encodev does the same, but for a struct iovec instead of a character buffer.

int sasl_encode(sasl_conn_t *conn,
const char * input,
unsigned inputlen,
const char ** output,
unsigned * outputlen);
  Parameters

    - conn – is the SASL connection context

    - output – contains the decoded data and is allocated/freed by the library.

    - outputlen – length of output.

  int sasl_encodev(sasl_conn_t *conn,
  const struct iovec * invec,
  unsigned numiov,
  const char ** output,
  unsigned * outputlen);
  Parameters

    - conn – is the SASL connection context

    - output – contains the decoded data and is allocated/freed by the library.

    - outputlen – length of output.

## Return Value

SASL callback functions should return SASL return codes. See sasl.h for a complete list. `SASL_OK` indicates success.

Other return codes indicate errors and should be handled.
