Cryptography: Seof Golang encrypted os.file

**We dive into cryptography topics, filesystem internals, attack vectors and mitigations, etc.**

We explain the internals for seof.File a Golang drop-in replacement for os.File. As per its website https://github.com/kuking/seof : Encrypted drop-in replacement of golang' os.File, the file stored in disk will be encrypted, and the resulting type can be used anywhere an os.File could be used. i.e. it can be both sequentially and randomly read and write, at any file position for any amount of bytes, can be truncate, seek, stats, etc. i.e. Read, ReadAt, WriteAt, Seek, Truncate, etc.
