Online SHA1 hash Generator

When I try to load firebase Json file into my android project, I got this warning: Android studio warning: " this firebase json does not belong to this project". I thought I might have a problem with project, I created new clear project to test it but all the time same warning.PS. I did it successfully on my previous projects. I got this error around 1 week. And I realized that my android studio gives me the same SHA1 code for any project that I created.Appreciate for any help!

I have an android app with encryption SHA1 and I need to register users in WordPress/Woocommerce with SHA1.

In this mode I can register users with WordPress and make login in android app.

Is possible to make this with some code in php fuctions.php or plugin ?

thanks!

I need to implement AES-CBC encryption algorithm, but the example that I have creates the initialize IV manually:

//initialize IV  manuallybyte[] ivBytes = new byte[]{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00};

The AES-CBC that I have:

    package xxxx;    import javax.crypto.Cipher;    import javax.crypto.KeyGenerator;    import javax.crypto.SecretKey;    import javax.crypto.spec.IvParameterSpec;     import javax.crypto.spec.SecretKeySpec;    public class AES_CBC    {        public static void main(String[] args)        {            try            {                    //Lookup a key generator for the AES cipher                        KeyGenerator kg = KeyGenerator.getInstance("AES");                SecretKey key = kg.generateKey();                SecretKeySpec keySpec = new                        SecretKeySpec(key.getEncoded(), "AES");                   //Lookup an instance of a AES cipher               Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");      //initialize IV  manuallybyte[] ivBytes = new byte[]{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00};            //create IvParameterSpecobject              IvParameterSpec ivSpec = new IvParameterSpec(ivBytes);                 //Initialize the cipher using the secter key        cipher.init(Cipher.ENCRYPT_MODE, keySpec,ivSpec);           //Message to encrypt             String plainText = "This is a secret!";             //Sequence of byte to encrypt              //Encrypt the message                  byte[] cipherText = cipher.doFinal(plainText.getBytes());                System.out.println("Resulting Cipher Text:\n");                for(int i=0;i<cipherText.length;i++)                {                System.out.print(cipherText[i] + " ");                }                System.out.println("");                        } catch (Exception e)            {                e.printStackTrace();            } } }

Instead of setting IV manually, I would like to use the output of SHA-1 as the initialize IV, as each time I have different integer value I use SHA-1 to get fixed length and reuse it as initialize IV in AES, for example:

input : 10digest : b1d5781111d84f7b3fe45a0852e59758cd7a87e5

So, AES code needs 16Byte, and SHA-1 produces 20 Bytes, how can I transfer 20B to be fitted as 16 Byte in AES code?

How to reuse :b1d5781111d84f7b3fe45a0852e59758cd7a87e5 instead of 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00

SHA-1 produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as a hexadecimal number, 40 digits long, so is this (20-byte) of hex value as an array or just normal hex value?

This is my code: so what is the datatype of the output:

import java.security.MessageDigest; public class MessageDigestExample {public static void main(String[] args)throws Exception{String input = "This is a message";MessageDigest hash = MessageDigest.getInstance("SHA1");System.out.println("input : " + input);hash.update(Utils.toByteArray(input));System.out.println("digest : " + Utils.toHex(hash.digest()));

} }

I have this hex array of 20 Byte which the output [Digest] of SAH-1:

b1d5781111d84f7b3fe45a0852e59758cd7a87e5 

How can I reuse it as 16 Byte to be the initialize IV in AES_CBC encryption algorithm as this:

0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00
