subtls

Thanks, that’s a helpful summary. I knew about the ed25519 issue (but not the others) from writing this: https://github.com/jawj/subtls

https://github.com/jawj/subtls (A proof-of-concept TypeScript TLS 1.3 client) is implemented with the SubtleCrypto API. TIL about SubtleCrypto https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypt... : > The SubtleCrypto interface of the Web Crypto API provides a number of low-level cryptographic functions. Access to the features of SubtleCrypto is obtained through the subtle property of the Crypto object you get from the crypto property. decrypt() deriveBits() deriveKey() digest() encrypt() exportKey() generateKey() importKey() sign() unwrapKey() verify() wrapkey() Can SubtleCrypto accelerate any of the W3C Verifiable Credential Data Integrity 1.0 APIs? vc-data-integrity: https://w3c.github.io/vc-data-integrity/ ctrl-f "signature suite" > ISSUE: Avoid signature format proliferation by using text-based suit

Since I didn't know the acronym: https://en.wikipedia.org/wiki/Type%E2%80%93length%E2%80%93va... In fact, a key part of the subtls library is a simple class to make this relatively painless (it's currently just called `Bytes`, but perhaps something like `TLVCoder` would be a more informative). It reserves space for the length field, and provides a callback to write it automatically once you're done writing the value: https://github.com/jawj/subtls/tree/main#navigating-the-code. It also enables the indented and annotated output options.
