What is Code Signing?

Code signing is the process of authenticating software code/application/program/scripts to confirm the source of origin of the publisher and assure that the code has not been tampered or altered since it was signed.

Certificate Authorities (CA) confirm authenticity of the source of the code signing and then bind their public key to a certificate for code signing. This certificate allows verification of code signatures using the authentic certificate of origin. Code sign can be used to fulfill to the following three purposes:

It provides authentication for code
Protects your cryptographic information
Software/code author validation

The top 5 advantages that come with “Code Signature”:

Let’s an overview of the top 5 advantages that users can reap with Code signing

Verifies integrity of code Code signing allows an integrity test of the code with the help of hash functions. Hash function is employed at the source of the code, and that hash must be used at the point of delivery. This proves integrity of code. If the hash cannot be compatible, users will be warned about security issues or the code won’t download.

Verification is possible with a timestamp, too. Certificates for signing codes could include an the option of a time stamp. The time stamp data strip is included with the signature at the time of signing. This ensures the authenticity of the certificate at the time of signature.
The company’s reputation and authenticity is guaranteed: using the code signing to authenticate and verification of code, software or software eliminates the possibility of corruption or tampering with programs. This safeguards the reputation of the business and intellectual property.

Building trust between the two aspects of the exchange, firms will gain more from clients who trust their software programs such as files, documents etc. for download. For download. is likely to see a significant growth in the amount of customer loyalty.
Revenue growth: Currently software publishers as well as platform providers are increasingly requiring the signing of code process through a trusted source/certificate authority (CA) for the distribution of software to users.

This is especially advantageous for smaller companies or developers who are looking to earn confidence from customers by being authentic and boost their brand’s visibility and also revenues.
Secure and safe user experience: As previously discussed within one point discussed in the previous paragraph, the code signing process establishes trust between those involved i.e. both the seller and the user. In addition those who purchase code-signed software or files are guaranteed security since the code is validly authenticated and validated, which will prevent code tampering.

Furthermore, code signing can provide a smooth user experience because there will be less security alerts and failures in installation when code is signed by a an authority that is trusted.
Integration seamless across multiple platforms: The code signing is now accessible across multiple platforms, including Apple iOS, Windows, Linux, Android, JAVA, Adobe AIR etc. A majority of these platforms strongly recommend the code signing process to distribute code.

A lot of browsers require the signing of code using certificates from a trusted certificate authority. It will also refuse any action commands that are provided by non-trusted sources. An interesting point is that Microsoft office macros as well as Firefox browser extensions are also required to have the signing of code.
