Certificate Utilities

Utilities to manage .tlv and .sgn files.

• tlvfile - Parse or build .tlv files (eg: ITLFile.tlv).
• sgnfile - Parse or build .sgn files.
• stripsgn - Remove .sgn header from a firmware file.
• certhash - Hash an x509 certificate and output as base64.
• enccnf - Encrypt or decrypt SEPMAC.cnf.xml files.
• mkcert - Make self-signed X509 certificates.

See Device Security for example usage.

Requirements

The following non-standard Python modules are required: crytography and lxml.

You can use the packages provided by your OS distribution or run sudo pip3 install -r requirements.txt to satisfy those dependancies.

sudo cp certhash enccnf mkcert sgnfile stripsgn tlvfile /usr/local/bin

Optionally, install the bash tab-completion helpers.
