    In this article, we will find out some possible reasons that might cause file system encryption in Linux and then I will provide some possible recovery methods that you can try to solve this problem. Introduction. fscrypt is likely to be a library that filesystems link to to support transparent file and directory security. Note. “fscrypt” in this document refers to the entire kernel-level part implemented in fs/crypto/, as opposed to the user-space fscrypt product.
