Online SHA1 hash Generator

Does anyone know how to transition authentications on NTP? I've done copious amounts of research, none being fruitful. For example, NTP currently using MD5, how do you move over to SHA1?

I am looking to access a local instance of Couchbase Server through its REST API. The HTTP GET requests are sent from Java.

The problem I am currently running into has to do with authorization.Specifically, I have managed to use Couchbase's Basic Authorization, but only by obtaining the hashed credentials (bG9jYWw6dHdlZXRzOnBBc3Mx in the example linked to above) by monitoring a Couchbase browser session using Chrome's developer tools and inspecting the request headers.

Now, another Couchbase article mentions that Couchbase uses SHA-1 in compliance with SCRAM. However, no mention is made of how to obtain the 'salt' and 'iterations' parameters from Couchbase. Which, I assume I need to go from the credentials to the challenge solution (i.e. hashed string)

So, the question is as follows: how to get from the credentials (user="local:tweets", pass="pAss1") (from the example of the first link) to bG9jYWw6dHdlZXRzOnBBc3Mx?

Thanks in advance,

Recently I am facing an issue to migrate an older android keystore. I searched lot but didn't get a solution.

I have an application with older MD5 hashed keystore(the keystore created on 2014). But now I want to upgrade the SHA hashing on the keystore without failing Application upgrade. Is this is possible?.

In SHA1, the hashing algorithm is weak that is why I am looking to upgrade obsoleted MD5 to SHA256/512.

I change my PC and I'm trying to update my app. I download a hole code from GIT but aplications now have different SHA1. How to change it ? There is an easy way ?

Innocently， I thought "SHA1withRSA algorithm" was simply operating the plainText with "SHA1", and use RSA/pkcs1padding to encrypt the result of "SHA1"。However, I found I was wrong until I wrote some java code to test what I thought. I use RSA publickey to decrypt the signature which I use the corresponding privatekey to sign with "SHA1withRSA algorithm" . But I found the result is not equal to "SHA1(plainText)", below is my java code:

    String plaintext= "123456";    Signature signature=Signature.getInstance("SHA1withRSA",new BouncyCastleProvider());    signature.initSign(pemPrivatekey);    signature.update(plaintext.getBytes());    byte[] sign = signature.sign();    //RSA decode    byte[] bytes = RsaCipher.decryptByRsa(sign, pemPublickey);    String rsaDecodeHex=Hex.toHexString(bytes);    System.out.println(rsaDecodeHex.toLowerCase());    String sha1Hex = Hash.getSha1(plaintext.getBytes());    System.out.println(sha1Hex);    //rsaDecodeHex!=sha1Hex

Easy to find that rsaDecodeHex!=sha1Hex, where

rsaDecodeHex=3021300906052b0e03021a050004147c4a8d09ca3762af61e59520943dc26494f8941b

and

sha1Hex=7c4a8d09ca3762af61e59520943dc26494f8941b 。

So, What's the detail in "SHA1withRSA" ?
