Defined in: packages/common/src/Crypto.ts:180

Derives a 32-byte key from a seed and a path using SLIP-21.

Derived keys are no stronger than the seed. A 16-byte seed gives 128 bits of security, or about 64 against a quantum computer, whatever the output length. Use a 32-byte random seed for keys that must stay safe against a quantum computer.
