The seccure toolset implements a selection of asymmetric algorithms
based on elliptic curve cryptography (ECC). In particular, it offers
public key encryption / decryption and signature generation /
verification. ECC schemes offer a much better key size to security
ratio than classical systems (RSA, DSA). Keys are short enough to make
direct specification of keys on the command line possible (sometimes
this is more convenient than the management of PGP-like key
rings). seccure builds on this feature and therefore is the tool of
choice whenever lightweight asymmetric cryptography -- independent of
key servers, revocation certificates, the Web of Trust, or even
configuration files -- is required.
The toolkit implements Diffie-Hellman key exchange, allowing you to agree a
key with another party over an insecure channel. The Diffie Helman protocol
affords forward secrecy, and requires no previous contact with the other
The seccure toolset allows you to select the curve that the operations are
performed on, so that different cryptographic needs can be supported. This
is currently the only ECC package in Debian GNU/Linux to offer a choice of
curves and MAC lengths.
It is currently missing some of the functionality of the sks-ecc package,
including encrypting to multiple recipients at once, and creating different
signature formats.

seccure (0.3-3) unstable; urgency=low
* Modify the patch added in the last upload to enable gcrypt's secure
memory, as apparently not disabling it is different to enabling it.
(Closes: #489835)
2008-08-06 - James Westby <>
seccure (0.3-2) unstable; urgency=low
* Make failure to mlock all memory only a warning, and re-enable gcrypt's
memory locking. Changes in pam since etch mean that the kernel's defaults
for memory locking are now respected, and seccure tries to lock more
memory than that, which means that the program can't be started. The patch
is from the upstream author, who considers it a stop-gap, but doesn't
anticipate having a proper fix before lenny. (Closes: #489835)
* Don't ignore "$(MAKE) clean" errors. The normal reason for this is the use
of autotools leading to the makefile not necessarily being present when
the clean target is run, be this package doesn't use autotools, so that
won't happen.
* Add a description to debian/patches/10-man-hyphen.dpatch.
* Update the standards version to 3.8.0 (no changes required).
* Release team: this isn't the diff that I sent you, I apologise. My sponsor
suggested that fixing these small things wouldn't be a problem.
