RandomCryption.js解密异常求助：随机加密系统解密功能修复

Hey there! Let's tackle this decryption issue head-on—sounds like you're dealing with two frustrating problems: either decryption fails entirely, or your output ends up cluttered with bits from your encryption variables.

First, let's cover some quick, common culprits that might be causing this, but sharing your encryption and decryption code snippets will let us nail down the exact issue. In the meantime, check these key areas:

• PRNG State Mismatch: If you're using a pseudorandom number generator, you need to initialize it with the exact same seed/state during decryption as you did during encryption. If the random sequence doesn't line up, you'll get garbled data or leftover bits from encryption variables.
• Variable Scoping/Reset Issues: Make sure encryption-specific variables (like buffers, counters, or temporary random value holders) are properly cleared or reinitialized before running decryption. If these variables retain old data from encryption, they can leak into your decrypted output.
• Padding Handling Errors: If you added padding to your data during encryption (to match block sizes, for example), double-check that your decryption logic correctly strips this padding. Skipping this step often leaves extra, random-looking bits in the final text.
• Encoding Mismatches: When converting between strings and bytes, use the same encoding (like UTF-8) for both encryption and decryption. A mismatch here can cause partial data corruption or unexpected characters that look like encryption variable fragments.

Once you share your code, we can dive into the specifics and get your decryption working smoothly.
