About Random Binary Generator
Random Binary produces a string of random 0s and 1s of the number of bits you set, with an option to group every 4 bits for readability. Useful for binary data samples, testing, or learning.
This is not a cryptographic randomness source. For secure random bytes use Random Bytes in the Cryptography category.
