Cryptography Tools

Official encryption library powered by zetrix-encryption-nodejs.

Generate New Keypair(zetrix_crypto_generate_keypair)

Generate new key pair with address.

Purpose: Create cryptographically secure keypair for new accounts.

Algorithm: Ed25519 (Edwards-curve Digital Signature Algorithm)

Returns:

{
  "privateKey": "priv...",
  "publicKey": "b001...",
  "address": "ZTX..."
}

Key Length: 256-bit private key, 256-bit public key

Security: Industry-standard algorithm used by cryptocurrencies worldwide

Performance: Generates keypair in <10ms

Offline: Completely offline operation, no network required

---

Public Key(zetrix_crypto_get_public_key)

Derive public key from private key.

Purpose: Calculate corresponding public key from private key.

Algorithm: Scalar multiplication on Ed25519 curve

Mathematics: P = s*G where P is public key, s is private key, G is generator

Deterministic: Same private key always produces same public key

Performance: <5ms computation time

---

Account Address(zetrix_crypto_get_address)

Get Zetrix address from public key.

Purpose: Derive Zetrix address from public key.

Process:

1. PublicKey → SHA-256 hash

2. → RIPEMD-160

3. → Checksum

4. → Base58 encoding

Format: Starts with "ZTX", 35 characters total

Checksum: Built-in error detection prevents typos

One-way: Cannot reverse address to get public key

---

Validate Key Format & Integrity(zetrix_crypto_validate_key)

Validate key or address format.

Purpose: Check if key/address string is correctly formatted.

Validates:

• Format

• Prefix

• Length

• Encoding

• Checksum

Checks Performed:

• Private key: "priv" prefix, 64 hex chars, valid curve point

• Public key: "b001" prefix, valid encoding

• Address: "ZTX" prefix, 35 chars, valid Base58, checksum

Performance: <1ms validation time

---

Generate Digital Signature(zetrix_crypto_sign)

Sign a message with private key.

Purpose: Create cryptographic signature proving message authenticity.

Algorithm: Ed25519 signature scheme (EdDSA)

Output: 64-byte signature (128 hex characters)

Security: Signature proves private key holder approved the message

Properties:

• Deterministic

• Non-repudiable

• Verifiable

Performance: ~0.5ms per signature

---

Verify Digital Signature(zetrix_crypto_verify)

Verify signature against message.

Purpose: Confirm signature was created by claimed private key.

Input:

• Message

• Signature

• Public key

Output: Boolean (valid/invalid)

Security: Mathematically impossible to forge valid signature without private key

Performance: ~1ms per verification (slightly slower than signing)

---

Encrypt Private Key(zetrix_crypto_encrypt_key)

Encrypt private key with password.

Purpose: Secure private key storage using password-based encryption.

Algorithm: AES-256-CBC (Advanced Encryption Standard)

Key Derivation: PBKDF2 with 10,000+ iterations and random salt

Output: Encrypted key + salt + IV in single string

Password Requirements:

• Minimum 12 characters

• Mixed case (upper and lower)

• Include numbers and symbols

• Avoid common words

Performance: ~100-200ms (intentionally slow for security)

---

Decrypt Private Key(zetrix_crypto_decrypt_key)

Decrypt encrypted private key with password.

Purpose: Recover private key from encrypted storage.

Process:

1. Extract salt/IV

2. Derive key with PBKDF2

3. Decrypt with AES-256

Validation: Automatically verifies decryption succeeded

Errors: Returns error if password incorrect or data corrupted

Performance: ~100-200ms (same as encryption)
