Gronsfeld Cipher client-side ?
How to use Gronsfeld CipherThe Gronsfeld cipher is a variant of the Vigenère cipher where the key is a sequence of digits instead of a word. Each digit (0 to 9) gives the shift to apply to the matching letter of the text, and the key repeats across the whole message. Enter a numeric key to encrypt or decrypt. Like Vigenère, it's a historical polyalphabetic cipher, processed client-side

Frequently asked questions
How is it different from Vigenère?
The key is numeric (0-9) instead of a word. Each digit gives the shift directly, whereas Vigenère first converts the key's letters into shifts
Can shifts exceed 9?
No, each key digit gives a shift of 0 to 9. For larger, more varied shifts use Vigenère instead
