Identifier

The Identifier is a /// semi-opaque structure (just bytes) to track keys within the Keychain.

// Size of an identifier in bytes
pub const IDENTIFIER_SIZE: usize = 10;

BlindingFactor

随机数，混淆因子

BlindingFactor is a useful wrapper around a private key to help with /// commitment generation.

pub struct BlindingFactor([u8; SECRET_KEY_SIZE]);

SplitBlindingFactor
