The SRP support will not be removed in 3.x releases. At the earliest it
could be removed in 4.0 release. Whether there will be a replacement
for the deprecated SRP APIs at that time we cannot currently say.
So unless you absolutely require not using deprecated APIs you can
still move to 3.x releas
I'm also interested in the answer to these questions regarding SRP in
OpenSSL v3.
Our project still uses OpenSSL v1.1.1 with plans to move to v3 next year.
However we use SRP extensively and will not be able to move to v3 if SRP
support is soon to be no longer available.
