/**
 * Generate a random id of designated length - using cryptographic secure random numbers,
 * so it is a bit slower than `randomId`
 *
 * @remarks
 *
 * This method differs from `crypto.randomUUID()` in the way that it can be of any specified length
 * and doesn't contain any "-".
 * The methods would be slightly slower than `randomId` since it is using `crypto.getRandomValues()`,
 * but it is a more secure method.
 *
 * @param length - The desired length of the id (minimum 2)
 * @returns A random generated id of a specified length
 *
 * @example
 *
 * ```ts
 * randomCryptoId(); // --> eg. 'efuc6f1n4xf'
 * randomCryptoId(20); // --> eg. '3vsmrbxlh9at0vhcsf1xh'
 * ```
