The other answer is only for Zip archive using AES, which might not be the case here.

comment How to safely renew user and CA certificates in a PKI
A 2048-bit RSA key ought to be fine until (at least) year 2030 or 2040 (depending on who you ask). More frequent key renewal is an old tradition, but it does not make sense with modern systems (it is a tradition established at times before the advent of the computer). Really, you need to update a key when it becomes conceivable that it might be cracked in practice, and with a 2048-bit RSA key this will not happen soon.

comment Can not open my yahoo email. The connection was interrupted
Somebody else had a problem with Yahoo, with symptoms compatible with yours. Maybe some ill-informed developer at Yahoo! botched his code recently. cf security.stackexchange.com/questions/63719/…
