Description
Currently is possible to derivate a user-password to a AES key, using the PBKDF2. However, it's not possible to create a ECDSA key.
I think it's possible to take the PBKDF2 result and create the ECDSA key. If it's a invalid point, throw a return a error.
Currently the WebCrypto don't support EdDSA (Ed25519 for instance), which is bad. The EdDSA seems easier to implement than ECDSA,

Research direction
The issue proposes deriving ECDSA or EdDSA keys from PBKDF2 output and notes that WebCrypto lacks EdDSA support. Start by reviewing the existing PBKDF2, ECDSA, and key-generation specification sections; clarify invalid-point behavior and the intended EdDSA scope. Done requires an agreed specification and corresponding tests, but no files or tests are named here.
