What me get is that the bloom of hundreds DELPHI custom components for

OpenSSL is no standard. If you want to use openssl enc with
tsymciphercryptohandler the parameters of tsymciphercryptohandler must
match
the parameters used by openssl enc. Default MSEgui keygeniterationcount
is 5
(I'll change it to 1), enc uses 1. Default MSEgui keylength is 0 (use

Where is the result format of the openssl enc command defined?

Especially how

The commands are as follows :

You propably need to compare a hash value of the original data with the

Are there related error codes ?
