This commit updates both README.md and the nwipe(8) manpage to reflect the
features and behaviour introduced in the upcoming v0.40 release. Changes include:
- Added documentation for the new AES-256-CTR PRNG and its hardware-accelerated
implementation.
- Updated erasure method list to include the BMB21-2019 State Secrets Bureau
sanitisation standard.
- Added full documentation for large, aligned I/O buffers and their impact on
performance.
- Documented the new I/O mode system (`--io-mode=auto|direct|cached`,
`--directio`, `--cachedio`) and the interaction with O_DIRECT fallback logic.
- Updated sync behaviour description to match the new byte-accurate scaling for
cached I/O.
- Updated PRNG section to remove the “future release” note for AES-CTR.
- Documented improved device exclusion with `/dev/disk/by-id/*` support.
- Updated seeding description to reflect the use of `getrandom()` instead of
`/dev/urandom`.
- Refreshed dependency lists and provided concise installation instructions for
multiple Linux distributions.
- Minor stylistic cleanup, clarification of SSD limitations, and improved README
structure for readability and accuracy.
You can now specify --pdftag to enable the
display of system UUID and system serial
number information on the PDF report.
Nwipe defaults to not displaying system IDs
but some users like to record the system UUID
or serial number on the Erasure Report along
with the disk information.
Manpage is named nwipe.1 which would be correct but manpage
contains section 8 which forms a mismatch(warning) in Debian.
# Man sections
1 Executable programs or shell commands
2 System calls (functions provided by the kernel)
3 Library calls (functions within program libraries)
4 Special files (usually found in /dev)
5 File formats and conventions, e.g. /etc/passwd
6 Games
7 Miscellaneous (including macro packages and conventions), e.g. man(7), groff(7), man-pages(7)
8 System administration commands (usually only for root)
9 Kernel routines [Non standard]
