<h2>Description</h2>
|
||||
|
||||
<p>ssss is an implementation of Shamir's Secret Sharing Scheme. The
|
||||
program suite does both: the generation of shares for a known secret,
|
||||
and the reconstruction of a secret using user-provided shares.</p>
|
||||
|
||||
|
||||
|
||||
<h2>Commands</h2>
|
||||
|
||||
<p><b>ssss-split</b>: prompt the user for a secret and generate a set of
|
||||
corresponding shares.</p>
|
||||
|
||||
<p><b>ssss-combine</b>: read in a set of shares and reconstruct
|
||||
the secret.</p>
|
||||
|
||||
|
||||
|
||||
<h2>Options</h2>
|
||||
|
||||
|
||||
|
||||
<p><b>-t <em>threshold</em></b></p>
|
||||
<p>Specify the number of
|
||||
shares necessary to reconstruct the secret.</p>
|
||||
|
||||
|
||||
|
||||
|
||||
<p><b>-n <em>shares</em></b></p>
|
||||
|
||||
<p>Specify the number of shares to be generated.</p>
|
||||
|
||||
|
||||
|
||||
<p><b>-w <em>token</em></b></p>
|
||||
|
||||
<p>Text token to name shares in order to avoid confusion in case one
|
||||
utilizes secret sharing to protect several independent secrets. The
|
||||
generated shares are prefixed by these tokens.</p>
|
||||
|
||||
|
||||
|
||||
<p><b>-s <em>level</em></b></p>
|
||||
|
||||
<p>Enforce the scheme's security level (in bits). This option
|
||||
implies an upper bound for the length of the shared secret
|
||||
(shorter secrets are padded). Only multiples of 8 in the range
|

||||
<p>Quiet mode: disable all unnecessary output. Useful in scripts.

</p>
|

|
||||
warnings.</p>
|
||||
|
||||
|
||||
|
||||
<p><b>-D</b></p>
|
||||
|
||||
<p>Disable the diffusion layer added in version 0.2. This option
|
||||
is needed when shares are combined that where generated with
|
||||
ssss version 0.1.</p>
|
||||
|
||||
|
||||
|
||||
<p><b>-v</b></p>
|
||||
|
||||
<p>Print version information.</p>
|
||||
|
||||
|
||||
|
||||
|
||||
<h2>Example</h2>
|
||||
|
||||
<p>
|
||||
In case you want to protect your login password with a set of ten
|
||||
shares in such a way that any three of them can reconstruct the
|
||||
password, you simply run the command
|
||||
</p>
|
||||
|
||||
<p>
|
||||
ssss-split -t 3 -n 10 -w passwd
|
||||
</p>
|
||||
|
||||
<p>
|
||||
To reconstruct the password pass three of the generated shares
|
||||
(in any order) to
|
||||
</p>
|
||||
|
||||
<p>
|
||||
ssss-combine -t 3
|
||||
</p>
|
||||
|
||||
|
||||
|
||||
<h2>Notes</h2>
|
||||
|
||||
<p>
|
||||
To protect a secret larger than 1024 bits a hybrid technique has to be
|
||||
applied: encrypt the secret with a block cipher and apply secret
|
||||
sharing to just the key. Among others openssl and gpg can do the
|
||||
encryption part:
|
||||
</p>
|
||||
<p>
|
||||
openssl bf -e < file.plain > file.encrypted
|
||||
</p>
|
||||
<p>
|
||||
gpg -c < file.plain > file.encrypted
|
||||
</p>
|
||||
|
||||
|
||||
|
||||
|
||||
<h2>Security</h2>
|
||||
|
||||
<p>
|
||||
<b>ssss</b> tries to lock its virtual address space into RAM for
|
||||
privacy reasons. But this may fail for two reasons: either the current uid
|
||||
doesn't permit page locking, or the RLIMIT_MEMLOCK is set too
|
||||
low. After printing a warning message <b>ssss</b> will run even without
|
||||
obtaining the desired mlock.
