ssss(1) General Commands Manual ssss(1)NAME
ssss - Split and Combine Secrets using Shamir's Secret Sharing Scheme.
SYNOPSIS
ssss-split -t threshold -n shares [-w token] [-s level] [-x] [-q] [-Q] [-D] [-v]
ssss-combine -t threshold [-x] [-q] [-Q] [-D] [-v]
DESCRIPTION
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.
COMMANDS
ssss-split: prompt the user for a secret and generate a set of corresponding shares.
ssss-combine: read in a set of shares and reconstruct the secret.
OPTIONS -t threshold
Specify the number of shares necessary to reconstruct the secret.
-n shares
Specify the number of shares to be generated.
-w token
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.
-s level
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 from 8 to 1024 are allowed. If this option is ommitted (or the value given is
0) the security level is chosen automatically depending on the secret's length. The security level directly determines the length of
the shares.
-x Hex mode: use hexadecimal digits in place of ASCII characters for I/O. This is useful if one wants to protect binary data, like
block cipher keys.
-q Quiet mode: disable all unnecessary output. Useful in scripts.
-Q Extra quiet mode: like -q, but also suppress warnings.
-D Disable the diffusion layer added in version 0.2. This option is needed when shares are combined that where generated with ssss ver-
sion 0.1.
-v Print version information.
EXAMPLE
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
ssss-split -t 3 -n 10 -w passwd
To reconstruct the password pass three of the generated shares (in any order) to
ssss-combine -t 3
NOTES
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:
openssl bf -e < file.plain > file.encrypted
gpg -c < file.plain > file.encrypted
SECURITY
ssss 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 ssss will run even without obtaining
the desired mlock.
