🔐 PhraseCipher

Example:

Your phrase: Purple monkeys dance at midnight.

Your password: P2rpl3M0nk#7sD4nc3@tM1dn!ght

How it works:

• Your phrase is converted to PascalCase (each word capitalized)
• Each vowel (A, E, I, O, U, Y) alternates between number and special character
• 1st occurrence: A→4, E→3, I→1, O→0, U→2, Y→7
• 2nd occurrence: A→@, E→#, I→!, O→-, U→*, Y→%
• 3rd occurrence: Back to numbers, and so on...
• Consonants stay unchanged (keeping their capitalization from PascalCase)
• Note: For compatibility, quotes, backslashes, semicolons, angle brackets, and similar problematic characters are automatically removed
