[openssl-users] Checksum for openssl-1.0.2p download

[Chris Outwin]

I’m an OpenSSL newbie and this is my first post. I’m using OpenSSL for receipt validation in an iOS application.  

Is there a list of checksums to verify openssl download versions?  I believe I should be using openssl-1.0.2p.  Can openssl-1.1.1 be used in a production application yet?  Why doesn’t openssl-1.1.1 end with a letter of the alphabet? 

 Thank you very much.
