Issue in decryption crypto.subtle encrypted text using RSACryptoServiceProvider

Hi,

I am trying to use RSA public key using RSACryptoServiceProvider and use it for encryption through window.crypto.subtle but ending with Cryptography_OAEPDecoding upon decryption.

//Generating public key:

var cspParams = new CspParameters { KeyContainerName = containerName };

using (var rsa = new RSACryptoServiceProvider(cspParams))
{
var rsaparameters = rsa.ExportParameters(true);

var base64ModulusKey = GetModulusKey(rsaparameters);

return base64ModulusKey;
}

Encryption through window.crypto.subtle:

var jwk_base64 = base64ModulusKey.replace(/\+/g, '-').replace(/\//g, '_').replace(/\=+$/, '');

window.crypto.subtle.importKey(
"jwk",
{
kty: "RSA",
e: "AQAB",
n: jwk_base64,
alg: "RSA-OAEP-256",
ext: true,
},
{ name: "RSA-OAEP", hash: { name: "sha-256" } },
false,
["encrypt"]);

window.crypto.subtle.encrypt(
{
name: "RSA-OAEP"
},
cryptoKey,
inputMessageBytes
).then(function(encrypted){
console.log("base64 encrypted text: " + arrayToBase64String(new Uint8Array(encrypted)));
});

//Decryption using private key:

using (var rsa = new RSACryptoServiceProvider(cspParams))
{
decryptedBytes = rsa.Decrypt(encryptedBytes, true);
}

Thanks in advance!
