Argon2 encryption in C# and decryption in Python

[Keveen-ghori]

My requirement is to generate hash from C# application and send that hash to the python application, and in python i want to compare it with plain text. Is it possible to implement?

I think this library doesn't need such functionality. Use the Base64 or HEX serialization formats for the byte array if you want to send the hash to another application.

For e.g., popular encoded form:

public string Hash(byte[] password)
{
    var salt = []; // generate random salt
    using var argon2 = new Argon2id(salt.Concat(password));
    var hash = argon2.GetBytes(192);
    
    // v - argon2 version
    // m - memory cost
    // t - iterations
    // p - parallelism factor
    return $"$argon2id$v={v}$m={m},t={t},p={p}${Convert.ToBase64String(salt)}${Convert.ToBase64String(hash)}";
}
