Re: [Users] freeswan-certificate problem

Ok, the largest positive integer a 32 bit signed int variable can represent is

2^31 -1 = 2'147'483'647

On a Linux/Unix system dates are stored in elapsed seconds since Epoch (Jan 1, 1970).

2'147'483'647 seconds = 596'523 hours = 24'855 days

68 years + 17 days

Jan 1 1970 + 68 years + 17 days = Jan 18 2038

Thus the limitation in openssl is not due to ASN.1 UTCTIME coding but to 32 bit integer arithmetic.

Regards

Do you need help?
