Encryption and decryption in SHA1Managed

private string Encrypt(string Data)
{
 SHA1Managed shaM = new SHA1Managed();
 Convert.ToBase64String(shaM.ComputeHash(Encoding.ASCII.GetBytes(Data)));
 byte[] eNC_data = ASCIIEncoding.ASCII.GetBytes(Data);
 string eNC_str = Convert.ToBase64String(eNC_data);
 return eNC_str;
}
//Encrypt

private string Decrypt(string Data)
{
 byte[] dEC_data = Convert.FromBase64String(Data);
 string dEC_Str = ASCIIEncoding.ASCII.GetString(dEC_data);
 return dEC_Str;
}
//Decrypt

C# SHA-2 Cryptography: SHA-256, SHA-384, SHA-512

Here are some crypto methods for SHA256, SHA384, and SHA512 which I had not posted about before. This is the class I am using.

using System.Security.Cryptography;
using System.Text;

public class clsCrypto {
public clsCrypto() {
}
public static string md5encrypt(string phrase) {
UTF8Encoding encoder = new UTF8Encoding();
MD5CryptoServiceProvider md5hasher = new MD5CryptoServiceProvider();
byte[] hashedDataBytes = md5hasher.ComputeHash(encoder.GetBytes(phrase));
return byteArrayToString(hashedDataBytes);
}
public static string sha1encrypt(string phrase) {
UTF8Encoding encoder = new UTF8Encoding();
SHA1CryptoServiceProvider sha1hasher = new SHA1CryptoServiceProvider();
byte[] hashedDataBytes = sha1hasher.ComputeHash(encoder.GetBytes(phrase));
return byteArrayToString(hashedDataBytes);
}
public static string sha256encrypt(string phrase) {
UTF8Encoding encoder = new UTF8Encoding();
SHA256Managed sha256hasher = new SHA256Managed();
byte[] hashedDataBytes = sha256hasher.ComputeHash(encoder.GetBytes(phrase));
return byteArrayToString(hashedDataBytes);
}
public static string sha384encrypt(string phrase) {
UTF8Encoding encoder = new UTF8Encoding();
SHA384Managed sha384hasher = new SHA384Managed();
byte[] hashedDataBytes = sha384hasher.ComputeHash(encoder.GetBytes(phrase));
return byteArrayToString(hashedDataBytes);
}
public static string sha512encrypt(string phrase) {
UTF8Encoding encoder = new UTF8Encoding();
SHA512Managed sha512hasher = new SHA512Managed();
byte[] hashedDataBytes = sha512hasher.ComputeHash(encoder.GetBytes(phrase));
return byteArrayToString(hashedDataBytes);
}
public static string byteArrayToString(byte[] inputArray) {
StringBuilder output = new StringBuilder("");
for (int i = 0; i < inputArray.Length; i++) {
output.Append(inputArray[i].ToString("X2"));
}
return output.ToString();
}
}
