Take a plaintext and transform each character with the output
of a PRNG, with the seed being the key.
How easy is it to crack the resulting "ciphertext"?
Make your PRNG a ChaCha20 and make your seed random and 256-bit,
and you will be OK.
Also: ISAAC seems fit for this job:

Seed your CSPRNGs using KMACXOF256 on secret key and salt.
RC4 too is secure too if you remove the bias.
