# pskc\_set\_key\_data\_b64secret(3)

API function

## NAME

pskc\_set\_key\_data\_b64secret - API function

## SYNOPSIS

**#include \<pskc.h\>**

**int pskc\_set\_key\_data\_b64secret(pskc\_key\_t \*** *key***, const char \*** *b64secret***);**

## ARGUMENTS

- pskc\_key\_t \* key

  a **pskc\_key\_t** handle, from **pskc\_get\_keypackage()**.

- const char \* b64secret

  the base64 encoded secret to set.

## DESCRIPTION

Set the PSKC KeyPackage Key Data Secret value in base64 as a zero-terminated string.  The *b64secret* data is copied into the *key* handle, so you may modify or deallocate the *b64secret* pointer after calling this function.  The data is base64 decoded by this function to verify data validity.  On errors, the old secret is not modified.

## RETURNS

**PSKC\_BASE64\_ERROR** on base64 decoding errors, **PSKC\_MALLOC\_ERROR** on memory allocation errors, or **PSKC\_OK** on success.

## SINCE

2\.2.0
