Error occurred while decoding OAEP padding

Question

While decrypting text using RSACryptoServiceProvider.Decrypt, I am getting the error:

Error occurred while decoding OAEP padding.

Answer 1

FYI, you can still be (en/de)crypting in the right key sequence (encr:pub key, decr:priv key) - i.e. can still get this error decrypting with a private key - it just may be the wrong private key (i.e. from another cert/key pair), not the one paired w/ the pub key with which u encrypted initially. If u turn off OAEP padding and get a "bad data" exception, that's another indication.
