ChangePassword

ChangePassword method in the ABBYY FlexiCapture user management API resets a user password, with sample code for computing the salted SHA-256 password hash.

What it does

Definition

bool ChangePassword( string userName, string oldPassword, string newPassword );

Parameters

Name	Type	Description
userName	string	User name
oldPassword	string	Old password value (unencrypted)
newPassword	string	New password value

Sample code for calculating the password hash:

public static string GetPasswordHashWithSalt( string login, string password )
        {
            string salt = GetPasswordSha256Hash(login.ToUpper());
            return GetPasswordSha256Hash(password + salt);
        }
        private static string GetPasswordSha256Hash( string password )
        {
            Encoding enc = Encoding.GetEncoding("UTF-16");
            byte[] buffer = enc.GetBytes(password);
            var cryptoTransformSHA256 = new SHA256CryptoServiceProvider();
            string hash = BitConverter.ToString(cryptoTransformSHA256.ComputeHash(buffer)).Replace("-", "");
            return hash;
        }

Returned value

Type	Description
bool	”false” if the password has not been reset. For example, the old password didn’t match the new password ”true” if the password has been successfully reset
