2. Cryptography API

Our support code includes a custom crypto package which contains various cryptography primitives that may be useful for your implementation.

Important

As stated in Technical Requirements, all cryptographc functions must be performed using this API—you are not permitted to use any external cryptography libraries or other cryptographic primitives beyond those provided here.

The provided primitives are:

• 2.1. Asymmetric Encryption
• 2.2. Digital Signatures
• 2.3. Hash Functions and HMACs
• 2.4. Key Derivation Functions
• 2.5. Symmetric Encryption
• 2.6. Random Byte Generator
