Hello All,

 

Any insight on this would be greatly appreciated…  J

Subject: Is openssl 0.9.8r and openssl1.0.0 compatible ?

 

Hi All,

 

We have a Linux box1 (Client) that has openssl 0.9.8r.   That box communicates with a different kind of Linux box2 (Server) that has openssl 1.0.0e.

 

openssl0.9.8r  and  openssl1.0.0e  seem fairly happy together.

 

In the near future our 2nd Linux box is migrating to a new Platform, as a result, it will have  openssl1.0.0.

 

My question is: Should I anticipate any incompatibilities between those two versions of openssl (0.9.8r  -and-  1.0.0)?

 

Out of curiosity, what version(s) of   openssl1.0.X.Y   are most compatible (functionality-wise)  with the  openssl0.9.8r  version ?

 

Thanks a bunch.

If you're referring to the C API, I would not depend upon binary
compatibility. There are sometimes subtle changes that will cause
failures in corner cases that you won't discover unless your regression
tests are really good.

Insight: Recompile for each openssl update, even for a letter change.
