Authentication. Security. Trust. What is Code Signing?  Code Signing is the virtual equivalent of shrink-wrapping CD-based software for distribution.  Software developers digitally sign code or software distributed over the Internet using X.509 v3 digital certificates marked for the specific use of digitally signing code.  The digital certificate binds the identity of a person or entity to a public key which is related to a corresponding private key. The private key is used to apply a digital signature to a shortened version of the code which is run through a hashing algorithm. The public key is used to verify the signature.  Signing the hash of the code with an algorithm like SHA-1 provides a method to validate if the code has changed in any way since signature. Digital Certificate marked for Code Signing (Code Signing Certificate)

Authentication. Security. Trust.  Code Signing using a trusted third party prevents: − Users abandoning the installation of an application that is not easily identified as genuine. − Malicious alteration of legitimate code. − Identity theft or damage to reputation of vendor or code author.  The end user knows the digitally signed software being executed is legitimate, comes from a known software vendor and has not been tampered with since being published.  By digitally signing code, the software vendor enhances customer confidence, increasing the number of downloads. The Benefits of Code Signing Unsigned code The end user is presented with a warning message that may cause them to abandon the install. Signed code The code has been digitally signed by a certificate from a trusted Certification Authority. The end user is presented with the publisher’s identity.

Authentication. Security. Trust.  Different platforms have different requirements and options available for digitally signing code.

Authentication. Security. Trust.  There are several elements to consider when choosing the right Code Signing Certificate to sign your application. − Ubiquity Public rooted Code Signing Certificates, as opposed to self-signed certificates, will allow users to verify the authenticity of the publisher and origin of the software, as well as ensuring that the code has not been tampered with. − Timestamping services Timestamping ensures that the signature on your application remains valid after the certificate has expired. − Price and value Am I getting good value for the experience, support and functionality? − Trust A good reputation and credibility of the Authority can inspire additional downloads of your application. − Support for individuals and commercial software publishers Many Authorities only support commercial software publishers and not individuals.
