Zemer-Cipher is an Android library designed for YouTube cipher deobfuscation and PoToken generation, facilitating the extraction of streaming URLs from obfuscated JavaScript. Key features include signature cipher deobfuscation, n-parameter transformations to mitigate throttling, and remote-updateable player configurations that allow real-time updates without requiring app releases. This library is crucial for applications leveraging the YouTube API to maintain functionality amid frequent player script rotations.
