[Gpg4win-users-en] GPG4Win and FIPS 140-2 Compliant

[Gaurav Sharma]

Hi Bernhard,

Thanks for the information.

I am looking for an online documentation where I can find supported GPG4WIN
cipher blocks.

I can run gpg --version and system tells me about the supported algorithms
but I am looking to find out what cipher blocks GPG4Win supports:

For example: ECB, CFB, CBC, OFB, CTR, CCM, GCM, OCB, XTS, EAX

Is there any configuration setting we can use to pass the cipher block name?

Please advise. Appreciate the support.

*Thanks,*
