            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 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:

            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.

            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:

            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?

            ANSWER

            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.:
