 * APIKey represents a compound key consisting of four parts or segments:
 * - Prefix: A company or application identifier (e.g., "AGNTSTNP")
 * - Key: A UUID-based identifier encoded in Base32-Crockford
 * - Entropy: Additional segment of random data for increased uniqueness
 * - Checksum: CRC32 checksum of the previous components (8 characters)
 *
 * Format:
 *
 * 	[Prefix]_[UUID Key][Entropy]_[Checksum]
