#include <sasl/saslutil.h>

\fBint\fR \fBsasl_encode64\fR(\fBconst char *\fR\fIin\fR, \fBunsigned\fR \fIinlen\fR, \fBchar *\fR\fIout\fR,

.SH DESCRIPTION
.sp
.LP
Use the \fBsasl_encode64()\fR interface to convert an octet string into a base64 string. This routine is useful for SASL profiles that use base64, such as the IMAP (IMAP4) and POP (POP_AUTH) profiles. The output is null-terminated. If \fIoutlen\fR is non-\fINULL\fR, the length is placed in the \fIoutlen\fR.
