WebJan 6, 2024 · RSA 4096 w/ OAEP can only encrypt 446 bytes of data ( see 7.1 of RSA RFC 2437 ), and RSA 2048 w/ OAEP can only encrypt 245 bytes (still should be plenty of room for 16 + 32 bytes for IV and symmetric key). I don't see anywhere that you set the key length for the RSA provider, so it may be failing for some reason to encrypt the AES key. notice of disciplinary hearing template
