            ECSDA sign with Python, verify with JS
            Asked 2022-Apr-10 at 18:16

            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)




            Answered 2022-Apr-10 at 18:16

            The 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:

            Crypto-js encryption and Python decryption using HKDF key
            Asked 2022-Mar-28 at 11:29

            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.

            The 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:

            Chaum blind signature with blinding in JavaScript and verifying in Java
            Asked 2022-Mar-04 at 16:01

            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:



            Answered 2021-Dec-13 at 14:56

            The blind-signature library used in the NodeJS code for blind signing implements the process described here:

            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:

            Answered 2022-Mar-02 at 07:47

            The 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:

            Is it possible to get ISO9796-2 signature with Trailer = 'BC' in Javacard?
            Asked 2022-Feb-24 at 10:46

            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'?

            You can generate such signature using Cipher.ALG_RSA_NOPAD in decrypt mode.

            How to transfer custom SPL token by '@solana/web3.js' and '@solana/sol-wallet-adapter'
            Asked 2022-Jan-29 at 21:02

            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:

            1. Create a @solana/web3.js Transaction object and add instructions to it
            2. Sign the transaction with the wallet
            3. Send the transaction over a Connection

            Why are signatures created with ecdsa Python library not valid with coincurve?
            Asked 2021-Dec-25 at 14:41

            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?



            Answered 2021-Dec-25 at 14:41

            Bitcoin 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 raspiblitz

            If you are looking for a tutorial on how to organize a workshop to build the RaspiBlitz, see here.
            Every time you start with a fresh SD card image you will be offered different options. For example this is also the point where you can import a Migration file from an older RaspiBlitz - read about Migration further down. But because you are setting up a brand new RaspiBlitz you will choose here FRESHSETUP. Then you will be asked what to do with the connected hard drive/SSD. If there is already a blockchain on your hard drive/SSD you will be asked if you want to use this pre-synced/validated data or if its OK to delete it. If there is no blockchain data this question will be skipped. Finally you have to agree that all (other) data on the hard drive/SSD will be deleted, except the blockchain if you selected that previously. This might take some seconds.
            Once the basic setup has completed your lightning node will be setup & your lightning wallet will be created for you. As part of this process you will be presented with your lightning node "seed words" which you MUST write down on paper (or engrave into steel) and store in a secure location. You will need to confirm that you wrote the seed words down before you can continue. WRITE YOUR SEED WORDS DOWN before you continue - you will need them to recover funds in case of failing hardware etc. If you just want to try/experiment with the RaspiBlitz, at least take a photo of the seed words with your smartphone, so you have something just in case. If you plan to keep your RaspiBlitz running store this word list offline or in a password safe. You can use this RaspiBlitz Recovery Sheet (PDF) to write down your seed words for safe storage.
            A ready-to-use SD card image of RaspiBlitz is provided by us for download, to get everybody started quickly (see above). But if you want to build that image yourself - here is a quick guide:.
            Get a latest RaspiOS 64-bit: DOWNLOAD.
            Write the image to an SD card: TUTORIAL.
            Add a file called ssh to the root of the SD card when mounted on your laptop to enable SSH login.
            Start the card on a Raspi and login via SSH with ssh pi@[IP-OF-YOUR-RASPI]. Password is raspberry.
            Can I run RaspiBlitz on other computers than RaspberryPi?
            How can I build an SD card from another branch?
            How can I build an SD card from my forked GitHub Repo?
