The real question is do you encrypt-and-sign or sign-and-encrypt?

[–] Eufalconimorph@discuss.tchncs.de 20 points 1 year ago

Encrypt then sign. Always authenticate before any other operations like decryption. Don't violate the cryptographic doom principle.

Encrypt then sign. Verification is often much faster than (or at worst as fast as) decryption. Signature can also be verified without decryption key, making it possible to verify the data along the way.
