How to convert MessageDigest in C#

Hello,

I have Java code to convert into C#. Below is the code:

Java:

Java

final MessageDigest digest = MessageDigest.getInstance("SHA-1");
            digest.reset();
            digest.update(secretKey.getBytes("UTF-8"));
            
            final String key = new String(Hex.encodeHex(digest.digest())).substring(0, 32);

You can find the Hex.encodeHex from here.

My C# Code (incomplete) :

C#

var sha = new SHA1CryptoServiceProvider();
                string b64 = ByteArrayToString(Encoding.UTF8.GetBytes(secretKey));
                var b64Bytes = Encoding.UTF8.GetBytes(b64);

I think below two lines should be added in my C# code.

C#

var result = sha.ComputeHash(b64Bytes);
               var finalResult = BitConverter.ToString(result).Replace("-", "").ToLower();

For more information here, secretKey is a 16 letters long hexadecimal value. I need it's 32 bytes.

Thanks
Kapil

public String buildPasswordDigest(String nonce, String created, String appSecret)
{return base_64(sha_256(nonce, created, appSecret));}

public byte[] sha_256 (String nonce, String created, String appsecret)
{try{MessageDigest sha = MessageDigest.getInstance("SHA-256"); return sha.digest((nonce+created+appsecret).getBytes());}catch (NoSuchAlgorithmException e){throw new RuntimeException(e);}

public String base_64(byte[] bytes){return new String(org.apache.commons.codec.binary.Base64.encodeBase64(bytes));}

convert to C#
