/**
 * IDEncrypter allows to encrypt and decrypt a bigint using the aes-128-ctr
 * and complemented with some checksum validations:
 * - one checksum included inside the encrypted data
 * - a second one public, at the end of the returned string
 *
 * IDEncrypter returns a URL-safe base64-like string of 16 chars; that string
 * is composed of the chars: [A-Za-z0-9] - _ .
 * The last two chars represent a public checksum that you can validate using the
 * function isValidEncryptedID. If you copy the functions isValidEncryptedID and
 * checksumString outside of this file, you can use them in the user interface side.
 *
 * IDEncrypter constructor requires two strings of 16 chars of [A-Za-z0-9].
 * These strings work as a template for the passwords required during the encrypting
 * process. These strings are shuffles in order to generate very different encrypted
 * id even when they are sequential.
 *
 * For example, for: new IDEncrypter('3zTvzr3p67VC61jm', '60iP0h6vJoEaJo8c')
 * There are listed some numbers with the encrypted correspondent value:
 *
 *                        Without prefix | With prefix: 'co'
 *                   ID     Encrypted ID | Encrypted ID       ID

 * IDEncrypter support int64/long numbers generating an encrypted string

 * than the maximum of int64 (9_223_372_036_854_775_807) you will get encrypted
