in reply to Deterministic asymmetric encryption [Crypt::RSA]

What would the consequences be if I disregarded the advise...

As you've shown in your update, you'd get deterministic encryption — with the security disadvantages as (for example) mentioned in the Wikipedia article you linked to.

What I don't understand is what motivated you to want deterministic encryption in the first place, if you then ask what the consequences are? An XY problem? Or am I missing something?

    I want to be able to do database lookups on the encrypted text. I also want to understand the extent of the security consequences of using deterministic encryption. E.g. is the encryption highly insecure when padding is not used, or is it just marginally less secure?
