[Cryptix-users] help with cryptix openpgp

[Francisco J. R. L. <fra...@gm...>]

Hi everybody,

I am new with cryptography stuff and I am working on a program that needs to
encrypt and sign large files using cryptix openpgp, I am currently running
the samples GenereteAndWriteKey and StreamEncrypt, then I am going to run
StreamEncryptSign example.

I am working on Windows XP Professional, Java SE 5, MyEclipse 6.

For now, I have the following jar files in a lib folder in my MyEclipse
project:

certpath-api-compat.jar
cryptix-jce-provider.jar
cryptix-message-api.jar
cryptix-openpgp-provider.jar
cryptix-pki-api.jar

I have a question for the moment,

How a Key/Key pair can be generated with an expiration date?
In the GenerateAndWriteKey example, running on debug mode, in the
watch/inspect variables, each key, pubkey and privkey has a packet member;
this packet contains an expire member (int).

What does it mean that expiration date and what values are permitted to this
variable?

I guess the value 0 means never expires.

Regards and thank you for your time,
Francisco Rosas
