Does Nettle have APIs to hash a file/stream?

[Shifu Chen]

like following APIs:

• hexdigest("md5", open("data.txt"))
• hexdigest_file("md5", "data.txt")

[Elliot Saba]

I like your first idea best, so I have implemented it in 37e1c9a8

[Tony Kelman]

though it's best to use do block syntax to avoid leaking file descriptors
