The eslock file extension is associated with the ES File Explorer. The eslock file stores data encrypted by the ES File Explorer tool. The encryption uses AES-256 bit algorithm. The eslock files have the md5 checksum of the password. Simple passwords can be reversed from the md5 record. Use EsLockMD5Extractor tool to extract the password in MD5 hash from eslock file.
When you lock a file with the ES File Explorer app, the file is renamed to numbers and letters with the “eslock” extension. For example, asd496gfr04.eslock. You can open the eslock file only with the correct password in the ES File Explorer app that created it. ES File Explorer File Manager uses AES 256-bit encryption for the data. Without the password, the app won’t allow opening the encrypted eslock file.
ES File Explorer Encrypted files with eslock extension are commonly seen from Windows 10 devices in China. They are originally developed by ES APP Group for the ES File Explorer File Manager Android app.
