온라인 SHA256 해시 생성기

I'm trying to validate this message using a public key that I know is good. If I had the code in php or c++, that would be perfect. Ideally, I just need to know the data that is being used from the message.

Below is the sample message.

I am trying to connect to an API that uses an outdated hmac hash authentication mechanism for the API's.

For an instance:

$signature = hash_hmac('sha256', $string_to_sign, $api_sec);

vs the one generated in Go:

h := hmac.New(sha256.New, []byte(authSecret))h.Write([]byte(stringToSign))signature := hex.EncodeToString(h.Sum(nil))

When I use the same stringToSign($string_to_sign) and same authSecret($api_sec) the signature generated with Go results as an invalid signature for the API. But if I create the same with the PHP function it works fine. I am a bit lost as to where to look.

I really need help here ... I know this is simple ... but if someone could explain this like they are talking to a ten year old I'd appreciate it

• I converted a JPEG to SHA-256
• I submitted that SHA-256 hash to theblockchain using origin stamp
• Now, I want to manually convert myoriginal hash either from (Hex) or (Base64) into the "Address" givento me by originstamp so I can view the transaction on blockchain.infohow do I do this? I CANNOT figure it out.

In a C program, I can change the internal state of the SHA256 algo as follows:

SHA256_CTX c;SHA256_Init(&c);for (i =0; i<64; i++)    SHA256_Update(&c, "$", 1);# 0x44332211 is just for examplec.h[0] = htole32(0x44332211);c.h[1] = htole32(0x44332211);c.h[2] = htole32(0x44332211);c.h[3] = htole32(0x44332211);c.h[4] = htole32(0x44332211);c.h[5] = htole32(0x44332211);c.h[6] = htole32(0x44332211);c.h[7] = htole32(0x44332211);

Python provides hashlib.sha256. I want to ask if there is any way in which the internal state of sha256 algo can be updated in Python similar to what I did in C above ?

As a part of IEFT standard, I need to hash the body of a JSON request.

I have a reference code in JS that is known to produce the right hash, but now I'm stuck with matching the result in Python.

The JSON body:

body = {"description":"Test ticket"}

The JS code:

bodyHash = CryptoJS.SHA256(body).toString(CryptoJS.enc.Base64)

Please note it's not JSON.stringify(body)! The "correct" hash (the one I'm looking to match):

TqXFCKZWbnYkBUP4/rBv1Fd3e+OVScQBZDav2mXSMw4=

The Python solution should be along the lines of:

body_hash = base64.b64encode(hashlib.sha256(repr(body).encode('utf-8')).digest()).decode('ascii')

Which produces something different:

z0RpYmKAIfVibpSLJx/iRDZaNHJkJ2+rcenc1KEEAUw=

Is there even a way to match those hashes? How the JS object is hashed in CryptoJS?
