-------------------------+----------------------------------
When tor cannot find any existing keys, the --keygen flag crashes with a
segmentation fault. This is caused by using the return value of
`crypto_read_tagged_contents_from_file` for wiping the `encrypted_key`
array.
The solution is to use the array size as the size (like the `pwbuf`
array). The patch for review follows.
