Generates a cryptographically secure 256-bit (32-byte) encryption key suitable for creating encrypted indexes. 
func GenerateKey() ([]byte, error)

​
Returns

TypeDescription
[]byteA 32-byte encryption key suitable for use with encrypted indexes
errorAny error that occurred during key generation

​
Security

The generated key is cryptographically secure and suitable for production use:
  • Uses Go’s crypto/rand package for secure random number generation
  • Provides 256 bits of entropy (32 bytes)
  • Compatible with AES-256 encryption used by CyborgDB
This key must be persisted securely. For more information, see Managing Encryption Keys.

Example Usage

package main

import (
    "encoding/hex"
    "fmt"
    "log"
    
    "github.com/cyborginc/cyborgdb-go"
)

func main() {
    // Generate a new encryption key
    key, err := cyborgdb.GenerateKey()
    if err != nil {
        log.Fatal("Failed to generate key:", err)
    }
    
    // Convert to hex string for storage/transmission
    keyHex := hex.EncodeToString(key)
    fmt.Printf("Generated key: %s\n", keyHex)
    fmt.Printf("Key length: %d bytes\n", len(key))
}
