Acustica Audio Azure 2 2023 [WiN, MacOSX]

Azure2 is a true-to-life emulation of a passive, hand-made equalizer characterized by tube make-up stages and the finest transformers, making it ideal for a wide range of applications. The transparency and three-dimensional quality of the original hardware is simply unmatched in the industry. The life it can breathe into mixes, vocals, and instruments will astound you and its infinite possibilities will blow your mind. Compared to similar designs, it makes everything sound more “like a record.”

A witch says,

Library is completely decrypted, decompressed, DRM related bloat removed, and built to the clean one.

Acustica is using RC4 for encrypting Nebula2 image files (N2P, N2S, N2V). RC4 is outdated weak protection, thus deprecated in many software / libraries. Not good for both security and speed.

For the library encryption (used by software), simple XOR with key mangling is enough. By using SSE2, XOR crypt can process data by 16 bytes at once, which results good decryption speed. AES with hardware acceleration should be good too.

There are lots of better secured crypto. However, hackers can extract any crypto key in the desktop apps by using debugger. R2R has made tons of keygens for tons of crypto as you know. There are no good reason to use slow crypto in the audio plugins. Just use simple and faster one – or ditch crypto.
