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 the identity of the source of code signing and tie their public keys to a certificate of code signing. This certificate allows verification of code signatures using the authentic certificate of origin. The code sign process will serve to three main functions:
It provides authentication for code
Protects your cryptographic information
Software/code author validation
The top 5 advantages from “Code Signature”:
Let’s an overview of the top 5 benefits that people can get through 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 to sign code, and that hash must be used to the destination. This proves the integrity of the code. If the hash cannot be compatible, users will receive a security alert or code won’t download.
Verification can be done with a timestamp, too. Certificates for signing codes could include an the option of a time stamp. The time stamp data strip is added along with the signature at the moment of signature. This ensures the authenticity of the certificate as of the date of signature.
The company’s reputation and authenticity is guaranteed: using the codes signing processes for authentication and verification of code, software and/or programs reduces the chance of corruption or tampering with programs. This safeguards the reputation of the company and intellectual property.
In enhancing trust on both parties involved in the deal, businesses will gain more from clients trusting their software applications such as files, documents etc. for download. If the reputation grows, one can anticipate a substantial increases in customer loyalty.
Revenue growth: Currently software publishers as well as platforms for network services are increasingly requiring the signing of code process through a trusted source/certificate authority (CA) to distribute software to users.
This is especially advantageous for smaller companies or developers who are looking to earn trust from their customers due to authenticity and build their brand’s reputation and also revenues.
Safe and secure user experience: As mentioned within one point discussed above, the process of signing codes creates trust between of the participants i.e. the vendor and the consumer. In addition the users who utilize code-signed software or files can be assured of security since the code is validly authenticated and validated. This will prevent code tampering.
Additionally, code signing will provide users with a smooth experience because there will be reduced security warnings and failures in installation when code is signed by a an authorized certificate authority.
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 lot of these platforms recommend using code signing for distribution of code.
Some browsers will require certificates to sign code from a trusted certificate authority. It will also refuse any action commands that are provided from non-trusted sources. A fascinating fact is that Microsoft macros for office and Firefox browser extensions are also required to have signature of the code.
