Description
A record that implements the SHA-1 hash type.
THashSHA1 provides methods such as:
- Update: Updates the hash value with the provided data.
- GetHashString: Returns hash value of the provided String.
- GetHashStringFromFile: Returns hash value of the provided file.
- GetHMAC: Returns a String representation associated with the HMAC authentication (Hash-based message authentication code).
