GCM256 Encryption/Decryption Webapp

Demo: https://demo.gcm256.soogs.xyz

Demo limitations: see below screenshot

Purpose:

The webapp allows users to encrypt plain text or decrypt ciphertext into plain text.

Versions available:

Standard AES-256 CGM: Anyone with the Passphrase (key) can decrypt the ciphertext.
Enhanced AES-256 CGM: Uses a unique additional hardcoded hidden Key in conjunction with the variable Passphrase to result different ciphertext. The same exact version must be used to decrypt the ciphertext.
The experience is the same for both versions however the enhanced version gives an extra layer of security and peace of mind.

How to use: Encrypt plain text into ciphertext

Set a Passphrase (Key): “!?#Bobbys!?#Secret!?#Birthday!?#Bash!?#2026!?#”
Input Text: “This is my super-secret text that I need to encrypt and share with my buddy about Bobbys upcoming birthday.”
Output Result: "4yOmV6BRq3b9P63jOQkFlz6UGJkMrYPhk8QpxrmzeMPTo6KEajmLmYXyDuAoxTvKca7/N3ERsA05FxOX1cdVMUlTNKM31bQX1kQzy9lmDYVyg86G3Z41F1X3p432Dc0/6aYrMKWLFuaedFCidv8VyBg5AH1SlEvUdZlNmOcXLv5fnXdrBtx/HE1mnOYON8Am8duh1CqA"

How to use: Decrypt ciphertext into plain text

Set a Passphrase (Key): “!?#Bobbys!?#Secret!?#Birthday!?#Bash!?#2026!?#”
Note: we must use the original passphrase(key) to successfully decrypt the ciphertext.

Input Ciphertext: "4yOmV6BRq3b9P63jOQkFlz6UGJkMrYPhk8QpxrmzeMPTo6KEajmLmYXyDuAoxTvKca7/N3ERsA05FxOX1cdVMUlTNKM31bQX1kQzy9lmDYVyg86G3Z41F1X3p432Dc0/6aYrMKWLFuaedFCidv8VyBg5AH1SlEvUdZlNmOcXLv5fnXdrBtx/HE1mnOYON8Am8duh1CqA"

Output Result: “This is my super-secret text that I need to encrypt and share with my buddy about Bobbys upcoming birthday”

Error: Incorrect Passphrase (Key)

If the incorrect Passphrase is used the following message will appear:

Set a Passphrase (Key): “I used a different passphrase this time or got the passphrase wrong”
