Use it when you don't want to expose your database numeric ids to users. The permutations are collision-free and fully deterministic. The random-looking effect is due to encryption, not to a PRNG. The same boundary range with the same secret key will always produce the same output.

Disclaimer ---------- [](#disclaimer) The library should not be considered cryptographically strong or used to sensitive data. Credits ------- [](#credits) - The PostgreSQL extension by Daniel Vérité. - An article on how to obfuscate primary keys in databases. Alternatives ------------ [](#alternatives) - Another Format Preserving Encryption library supporting multiple ciphers (DES, AES and Camellia) but slower performance. - Generates YouTube-like ids from numbers. Can be limited to digit-alphabet, but returns strings like `"09284"` instead of safe integers. - Super-fast number obfuscation based on Knuth's integer hash. However, range can only be defined by 4-62 bits. License ------- [](#license) The MIT License (MIT).
