/dev/sha is an IPC interface for the SHA-1 engine that accepts IOS_Open, IOS_Close & IOCTLV commands.
Internally in IOS, it uses 2 FDs: one of 0x10001 normally calculating SHA-1 hashes and 0x10002 when dealing with HMAC key hashes (also based on SHA). Despite this, it is better to do an IOS_Open when using this resource.
