Hi all,
I having a problem with the openssl engine manipulation. At my program I
need crypt a text using the private key inside the engine and decrypt the
crypted text using the public key at the disc. To do it first I need setup
the engine, crypt the text and then free all engine instances to decrypt the
text using the public key stored at the hard disc.
The program need runs continuously, but at the second iteration the
following error occur:
1886:error:8806D064:eracom engine:PKC11_FINISH:already
loaded:hw_eracom.c:1507:
1886:error:2607E074:engine
routines:func(126):reason(116):eng_table.c:182:
The code is below. Someone already have this problem or one similar that?
Any idea why it happens?
