QUESTION
I'm trying to achieve the exact opposite of this here where I need to sign a payload in Python using ECDSA and be able to verify the signature in JS.
Here is my attempt, but I'm pretty sure I'm missing something with data transformation on either or both ends.
(Key types are the same as in the answer provided to the question above)
I've tried some other variations but nothing worked so far.
(The verification on JS returns False)
Python:
...ANSWER
Answered 2022-Apr-10 at 18:16The main problem is that both codes use different signature formats:
sign_payload() in the Python code generates an ECDSA signature in ASN.1/DER format. The WebCrypto API on the other hand can only handle the IEEE P1363 format.
Since the Python Cryptography library is much more convenient than the low level WebCrypto API it makes sense to do the conversion in Python code.
The following Python code is based on your code, but additionally performs the transformation into the IEEE P1363 format at the end:

Based on the example provided here on how to establish a shared secret and derived key between JS (Crypto-JS) and Python, I can end up with the same shared secret and derived key on both ends.
However, when I try to encrypt as below, I cannot find a way to properly decrypt from Python. My understanding is that probably I am messing with the padding or salts and hashes.

Answered 2022-Mar-28 at 11:29The issue is that the key is not passed correctly in the CryptoJS code.
The posted Python code generates LefjQ2pEXmiy/nNZvEJ43i8hJuaAnzbA1Cbn1hOuAgA= as Base64-encoded key. This must be imported in the CryptoJS code using the Base64 encoder:

QUESTION
I'm experimenting with Chaum's blind signature, and what I'm trying to do is have the blinding and un-blinding done in JavaScript, and signing and verifying in Java (with bouncy castle). For the Java side, my source is this, and for JavaScript, I found blind-signatures. I've created two small codes to play with, for the Java side:
...ANSWER
Answered 2021-Dec-13 at 14:56The blind-signature library used in the NodeJS code for blind signing implements the process described here:
BlindSignature.blind()generates the SHA256 hash of the message and determines the blind message m' = m * re mod N.BlindSignature.sign()calculates the blind signature s' = (m')d mod N.BlindSignature.unblind()determines the unblind signature s = s' * r-1 mod N.BlindSignature.verify()decrypts the unblind signature (se) and compares the result with the hashed message. If both are the same, the verification is successful.
No padding takes place in this process.
In the Java code, the implementation of signing the blind message in signConcealedMessage() is functionally identical to BlindSignature.sign().
In contrast, the verification in the Java code is incompatible with the above process because the Java code uses PSS as padding during verification.
A compatible Java code would be for instance:

We are trying to make a JWT token for Apple Search Ads using the KJUR jws library. We are using the API documents from Apple:
We are generating a private key (prime256v1 curve):
openssl ecparam -genkey -name prime256v1 -noout -out private-key.pem
Next we are generating a public key from the private key:
openssl ec -in private-key.pem -pubout -out public-key.pem
Next we setup the header and payload:
...ANSWER
Answered 2022-Mar-02 at 07:47The issue is caused by an incorrect import of the key.
The posted key is a PEM encoded private key in SEC1 format. In getKey() the key is passed in JWK format, specifying the raw private key d. The PEM encoded SEC1 key is used as the value for d. This is incorrect because the raw private key is not identical to the SEC1 key, but is merely contained within it.
To fix the problem, the key must be imported correctly. jsrsasign also supports the import of a PEM encoded key in SEC1 format, but then it also needs the EC parameters, s. e.g. here. For prime256v1 aka secp256r1 this is:
QUESTION
I trying to get the RSA signature as described in Annex A2.1 of EMV book 2. As I understand it was described in ISO9796-2 as scheme 1, option 1. So, the resulting signature should contain a Header equal to '6A' and a Trailer equal to 'BC'.
The algorithms ALG_RSA_SHA_ISO9796 and ALG_RSA_SHA_ISO9796_MR are the only suitable that I could find. But they acting like scheme 1, option 2 with a Trailer equal to '33cc'
Is it possible to get a signature with Trailer = 'BC'?

Hello I am trying to transfer a custom SPL token with the solana-wallet adapter. However i am having trouble getting the wallet's secret key/signing the transaction.
I've looked at these answers for writing the transfer code but i need to get the Singer and i have trouble figuring out how with solana-wallet adapter. These examples hardcode the secret key and since i'm using a wallet extension this is not possible.
How can you transfer SOL using the web3.js sdk for Solana?
How to transfer custom token by '@solana/web3.js'
according to this issue on the webadapter repo https://github.com/solana-labs/wallet-adapter/issues/120 you need to:
- Create a @solana/web3.js Transaction object and add instructions to it
- Sign the transaction with the wallet
- Send the transaction over a Connection
But i am having difficulty finding examples or documentation as to how to do step 1 and 2.
...ANSWER
Answered 2021-Dec-06 at 13:51So i found a way to do this, it requires some cleanup and error handling but allows for a custom token transaction via @solana/wallet-adapter.

QUESTION
I'm switching from the pure Python ecdsa library to the much faster coincurve library for signing data. I would also like to switch to coincurve for verifying the signatures (including the old signatures created by the ecdsa library).
It appears that signatures created with ecdsa are not (always?) valid in coincurve. Could someone please explain why this is not working? Also, it seems that cryptography library is able to validate both ecdsa signatures and coincurve signatures without issues, consistently.
What is even more confusing, if you run below script a few times, is that sometimes it prints point 3 and other times it does not. Why would coincurve only occasionally find the signature valid?
ANSWER
Answered 2021-Dec-25 at 14:41Bitcoin and the coincurve library use canonical signatures while this is not true for the ecdsa library.
What does canonical signature mean?
In general, if (r,s) is a valid signature, then (r,s') := (r,-s mod n) is also a valid signature (n is the order of the base point).
A canonical signature uses the value s' = -s mod n = n - s instead of s, i.e. the signature (r, n-s), if s > n/2, s. e.g. here.
All signatures from the ecdsa library that were not been successfully validated by the coincurve library in your test program have an s > n/2 and thus are not canonical, whereas those that were successfully validated are canonical.
So the fix is simply to canonize the signature of the ecdsa library, e.g.:

Install ha_nicehash
head over to your NiceHash account settings
Go into the API Keys menu
In this menu at the top, you'll find your Organisation ID which is required to later setup the integration in Home-Assistant
click CREATE NEW API KEY
This will present you with this popup:
:warning: Make sure you configure it like the above picture (DO NOT ENABLE ANY OF THE OTHER SETTINGS, this is at your own risk)
Click on GENERATE API KEY
This will give you 2 strings, note them down, you can't retrieve them later on: The Key The Secret
Validate the popup and enable the API Key (it will be through email)
Once that is done, head over to Home-Assistant and add the integration from the integration menu:.
Name: Give a name to your integration (it will also be used as part of some sensors)
Key and Secret: This is the key/secret you retrieved from the API Key creation
Org ID: This is the Organization ID
Currency Trigam: This is the trigram of the currency the BTC amount will be converted to (both sensors will exist, BTC and the selected currency)
You're all set :tada:
