Package fast implements the FAST (Format-preserving encryption And Secure Tokenization) algorithm, providing secure format-preserving encryption for arbitrary byte sequences. FAST is a cryptographic scheme that encrypts data while preserving its format and length. For example, a 16-byte string encrypts to another 16-byte string, maintaining the same structure as the original data. This makes FAST ideal for encrypting structured data like database fields, tokens, or identifiers without changing their format. FAST provides 128-bit security when used with AES-128. The algorithm is based on the research paper "FAST: Secure and High Performance Format-Preserving Encryption and Tokenization" (https://eprint.iacr.org/2021/1171.pdf). Key security properties: Tweaks provide domain separation, allowing the same key to be used for different purposes without compromising security: FAST is optimized for performance with: Typical throughput on modern hardware: Cipher instances are safe for concurrent use. The S-box pool is initialized once using sync.Once, making it safe to encrypt/decrypt from multiple goroutines. Package fast provides the FAST algorithm implementation for format-preserving encryption.
