API Key Management #

Security Implementation #

1. Encryption:

   // Example encryption process
   $encrypted_key = WP_AI_Workflows_Encryption::encrypt($api_key);

• AES-256-CBC encryption
• Secure key storage in WordPress database
• Salt-based key derivation

1. Storage Structure:

   [
       'openai_api_key' => 'encrypted_key_string',
       'perplexity_api_key' => 'encrypted_key_string',
       'openrouter_api_key' => 'encrypted_key_string',
       'firecrawl_api_key' => 'encrypted_key_string',
       'llamaparse_api_key' => 'encrypted_key_string'
   ]

3. Access Control:

• Administrator-only access
• Key masking in interface
• Automatic validation
