How To Fix seccure-sign: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu seccure-sign is provided by seccure package.

seccure is:

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 party.

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 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.

To fix this problem, we can install more using the command below.

sudo apt-get -y install seccure

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install seccure.

sudo apt -y install seccure

Or if you have aptitude installed you can use the following command.

sudo aptitude install seccure
