generateRandomBlindingFactor(): U128

Defined in: src/utils/miscellaneous.ts:471

Generates a cryptographically secure random 128-bit blinding factor.

Returns

U128

A random U128 value sampled from 16 bytes of cryptographic randomness.

Remarks

This function uses randomBytes(16) to obtain 16 bytes of entropy and then interprets the resulting Uint8Array as a little-endian 128-bit integer.

Blinding Factors: Blinding factors are random values used in cryptographic operations to prevent information leakage and enhance privacy. They are commonly used in:

• Commitments and hash-based constructions
• Zero-knowledge proof systems
• Randomized encodings
• Privacy-preserving protocols

The generated blinding factor can be used to blind sensitive values (such as viewing keys or secrets) before they are used in cryptographic operations, ensuring that the same value produces different outputs each time it's used.

Security: This function uses cryptographically secure random number generation to ensure the blinding factor is unpredictable and cannot be guessed or manipulated by attackers.

Example

const blindingFactor: U128 = generateRandomBlindingFactor();
console.log(blindingFactor.toString());

// Use the blinding factor in a commitment
const commitment = hash(secretValue, blindingFactor);
