The Yappifier is a word-based substitution cipher.

Instead of encrypting characters into symbols (like traditional ciphers), it converts each character into a randomly selected word from a large shuffled list. The result looks like a strange paragraph of unrelated words, hence yappifier.

The seed controls the randomization of the shuffled word database. The same seed always produces the same shuffled word lists, ensuring:

• Encryption with seed X can only be decrypted using the same seed X.
• Changing the seed completely changes the cipher output.

Or in simple terms: The seed is the password.
Different seed → different encryption.
Wrong seed → garbage decryption.

Herring Frequency determines how often the script injects fake “red herring” words into the encrypted output. Every time this interval is reached, filler words are added to make the ciphertext longer and more confusing.

Filler Count controls how many of these fake words are inserted at each herring interval. Together, these settings add noise to disguise real character boundaries and make pattern analysis significantly more difficult.
