Joseph and Rich: In the previous code I obviated the "len" initialization, but it was initialized; and I used what Rich said. The application did not crashed, but I got this error:
error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag I've not found any documentation about this error. Any help again?
