Unix `shred' destroys files "so that they can be recovered only with great difficulty with
specialised hardware, if at all". It is based on the method from the paper
"Secure Deletion of Data from Magnetic and Solid-State Memory",
Proceedings of the Sixth USENIX Security Symposium (San Jose, California, July 22-25, 1996).
We do not go to that length to re-implement shred in Python; instead, overwriting with a block
of random data should suffice.
See https://github.com/ansible/ansible/pull/13700 .

Note standard limitations of GNU shred apply (For flash, overwriting would have no effect
due to wear leveling; for other storage systems, the async kernel->filesystem->disk calls never
guarantee data hits the disk; etc). Furthermore, if your tmp dirs is on tmpfs (ramdisks),
it is a non-issue.
Nevertheless, some form of overwriting the data (instead of just removing the fs index entry) is
a good idea. If shred is not available (e.g. on windows, or no core-utils installed), fall back on
a custom shredding method.

a) Write the data bytes to given path
This is used to write a byte string to a file or stdout. It is used for
writing the results of vault encryption or decryption. It is used for
saving the ciphertext after encryption and it is also used for saving the
plaintext after decrypting a vault. The type of the 'data' arg should be bytes,
since in the plaintext case, the original contents can be of any text encoding
or arbitrary binary data.
When used to write the result of vault encryption, the val of the 'data' arg
should be a utf-8 encoded byte string and not a text typ and not a text type..
When used to write the result of vault decryption, the val of the 'data' arg
should be a byte string and not a text type.
:arg data: the byte string (bytes) data
:arg thefile: file descriptor or filename to save 'data' to.
:arg shred: if shred==True, make sure that the original data is first shredded so that is cannot be recovered.
:returns: None
