Describe the bug
Calling either ethers.utils.recoverAddress or ethers.utils.recoverPublicKey will complain that the sig is not 65 bytes.

Reproduction steps

ethers.utils.recoverAddress('0xd967f017af94fa0dd9d81f14c12378dea06b13158f4bd7ca7be3a73ccbcce4fd', '0x16a4c32d7e8de74161179375bac6384d40a13ad06512a2b999a992935d99ca9f18ae63ce6cfbefe1225952a241b8f21ee4a3554b7e028519ae0ad62b0fbf2277')

Yes, that certainly makes sense for me to include. ;)

This is now available in v5.6.

Try it out and let me know if there are any issues. :)

hi @ricmoo, any chance that ethers can sign a signature as a compact signature or convert a signature to a compact signature? Wasn't sure if that was supported yet but it seemed like it wasn't. Thanks!

[ricmoo]

You want utils.splitSignature(sig). :)

[sunwrobert]

utils.splitSignature(sig)

😮 Thanks!

[ricmoo]

This was added, so I'll close it. Please re-open or create a new issue if there are any problems.

Thanks! :)
