[Gambas-user] Usage of openssl.EncryptSalted

[Marco Ancillotti]

I'm trying to use cipher["DES3"].Encrypt in the place of EncryptSalted ( 
it seem to be the right call as it take key and iv ) but
it say that my key lenght is wrong.

Using:
Print "K :" & Cipher["DES3"].KeyLength
Print "IV:" & Cipher["DES3"].IvLength

I found that key length is 24 and iv is 8 but I have a key length of 48 
and a iv of 16 and shell openssl get those without any
problem.

Is that a bug ?

Thanks in advence,
Marco.
