Module crypto 

VCL Cryptographic Primitives

Low-level cryptographic helpers used internally by VCLConnection:

• KeyPair — Ed25519 signing/verifying key pair
• encrypt_payload — XChaCha20-Poly1305 AEAD encryption
• decrypt_payload — XChaCha20-Poly1305 AEAD decryption
• hash_data — SHA-256 hashing

Structs

KeyPair

An Ed25519 key pair used for signing and verifying VCLPacket signatures.

Functions

decrypt_payload

Decrypt ciphertext with XChaCha20-Poly1305 using the given key and nonce.

encrypt_payload

Encrypt data with XChaCha20-Poly1305 using the given 32-byte key.

hash_data

Compute a SHA-256 hash of data. Returns a 32-byte Vec<u8>.
