I have been doing some digging on case Insensitive encryption. I am reading this:
Get Exact Matching with Case-Insensitive Deterministic Encryption (Generally Available)
And it looks like this feature will be GA with the Summer 19 release. This feature will greatly come in handy, as it will allow us to encrypt fields marked as external IDs. Will this feature (encrypting External IDs) be generally available with that release as well? I just want to make sure my understanding is correct, before banking on this feature.
