<function>gcry_pk_encrypt</function> performs public key encryption
|
|
operations. The caller has to provide a public key as the &sexp;
|
|
<parameter>pkey</> and <parameter>data</> as a &sexp;
|
|
with just one MPI in it. The function returns a &sexp; which may
|
|
be passed tp to pk_decrypt.
|
|
Later versions of this functions may take more complex input data.
|
|
|
|
Returns: 0 or an errorcode.
