Azure key - using rsa (private and public key)



The idea is pretty simple, create a rsa key in azure. Use public key to encrypt. Then use private key to decrypt. Private key never leave the vault.

Here is the code for doing that.


If you're getting bad request? Please check to make sure you have added MSI to the keyvault access policy.


I had that many many times the following error message,

 Unhandled Exception: Microsoft.Azure.KeyVault.Models.KeyVaultErrorException: Operation returned an invalid status code 'BadRequest'

and the problem is due to, specifying foAEP to false, instead of true.


var encryptedText = rsa.Encrypt(byteData, fOAEP: true); // use to be false :(

The specified initialization vector (IV) does not match the block size for this algorithm

If you're getting  exception when trying to assigned key to a symmetric key and getting error message below :- The specified initialization vector (IV) does not match the block size for this algorithm And your code probably look like something below :- Then you need to go into debug mode and start looking into the supported size for IV as shown in diagram below :- As you can see, IV is 16 bytes, so you need to provide 16 bytes. The same goes for Key field too, if you're adding anything to it. As long as you provide a valid key size, then we're good and you're code will be ready.
