Subject Re: Re: Ant tasks to encrypt or decrypt passwords from property files

Hello Alexey,

thanks, this is interesting. I will try it.

I was also thinking about another solution, which would be to encrypt/decrypt using GnuPG,
and have GnuPG-agent supply the passphrase.

This would be used on a server where AnthillPro is running.

I wonder whether this supplying of passphrases by agents is supported by BouncyCastle.
