Function deriveP2BKBlindedPubkeys

deriveP2BKBlindedPubkeys(
    pubkeys: string[],
    keysetId: string,
    eBytes?: Uint8Array<ArrayBufferLike>,
): { blinded: string[]; Ehex: string }
Alpha
Blind a sequence of public keys using ECDH derived tweaks, one tweak per slot.
Parameters
- pubkeys: string[]
  Ordered SEC1 compressed pubkeys, [data, ...pubkeys, ...refund]
- keysetId: string
  Hex keyset identifier, bound into the tweak.
- OptionaleBytes: Uint8Array<ArrayBufferLike>
  Optional. Fixed ephemeral secret key to use (eg for SIG_ALL / testing)
Returns { blinded: string[]; Ehex: string }
Blinded pubkeys in the same order, and Ehex as SEC1 compressed hex, 33 bytes.

Remarks
Security note: "Ehex" must never be reused. Doing so would create linkability and leak privacy. The only exception is for SIG_ALL proofs, as all secret tags must match.

This is the Sender side API.

Throws
If a blinded key is at infinity.
