Title: Code signing
| Old | New | Line | |
|---|---|---|---|
| 1 | + | Every piece of code may contain viruses, spyware, trojan horses, backdoors, rootkits, keyloggers and other kinds of malware. The risk has dramatically increased with the advent of wide-area networks like the internet, where it is easy to download programs of unknown or unverified origin. | |
| 2 | + | ||
| 3 | + | One measure to reduce the effects of malicious code is that some modern operating systems require executables and scripts that have been downloaded from the internet to be signed with a developer's certificate. Code signing confirms the identity of the software author and guarantees that the code has not been altered or corrupted since it was signed by use of a cryptographic hash. Therefore, it ensures both authenticity and integrity of the executables. | |

| 10 | + | Code signing is required in [[Portal:iOS|iOS]] and modern versions of [[Portal:Mac|macOS]]. Microsoft implements for [[Portal:Windows|Windows]] a form of code signing based on Authenticode to include information about developers and their code with their programs through the use of digital signatures. | |
