However, instead of containing a photograph and the signature of the certificate&#8217;s owner, a digital certificate binds the owner&#8217;s public key to the owner&#8217;s private key.<\/p>\n<p>3SL (our full company name is Structured Software Systems Limited) has obtained a digital certificate from the CA Symantec that we can use to identify any file as being something that we have produced.<\/p>\n<h2>Cradle Systems Engineering Tool<\/h2>\n<p>3SL&#8217;s system engineering tool Cradle contains many executables and other files. These files are supplied as a single distribution file, such as:<\/p>\n<p>Cradle72_Setup.exe<\/p>\n<p>It is helpful to us, and to anyone who receives the Cradle software distribution or who looks at any executable that is claimed to be part of the Cradle system engineering tool, to know that:<\/p>\n<ul>\n<li>The distribution<\/li>\n<li>The files inside the distribution<\/li>\n<\/ul>\n<p>have come from 3SL and have not been changed in any way after they were created by 3SL.<\/p>\n<p>So, starting with Cradle-7.2, 3SL has digitally signed:<\/p>\n<ul>\n<li>The Cradle software distribution<\/li>\n<li>The executables inside the distribution<\/li>\n<\/ul>\n<p>with our digital certificate.<\/p>\n<h2>Benefits<\/h2>\n<p>Using a digital signature brings several benefits to anyone who installs or uses Cradle.<\/p>\n<h3>Anti-Virus Products<\/h3>\n<p>Occasionally, some AV products have incorrectly claimed that a file in Cradle contains a virus. These incorrect reports are called false positives.<\/p>\n<p>Now that Cradle executables are digitally signed, we expect that your AV product will report fewer false positives.<\/p>\n<h3>Installation<\/h3>\n<p>Since the Cradle installer is digitally signed, Windows will display the <em>friendly<\/em> blue User Account Control (UAC) dialog at the start of the Cradle installation:<\/p>\n<figure id=\"attachment_934\" aria-describedby=\"caption-attachment-934\" style=\"width: 300px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-934 size-medium\" src=\"https:\/\/www.threesl.com\/blog\/wp-content\/uploads\/2017\/03\/Installation-UAC-300x221.png\" alt=\"cradle system engineering tool digital signatures\" width=\"300\" height=\"221\" srcset=\"https:\/\/www.threesl.com\/blog\/wp-content\/uploads\/2017\/03\/Installation-UAC-300x221.png 300w, https:\/\/www.threesl.com\/blog\/wp-content\/uploads\/2017\/03\/Installation-UAC.png 456w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-934\" class=\"wp-caption-text\">Windows Detects 3SL in Cradle System Engineering Tool Installer<\/figcaption><\/figure>\n<p>instead of the <em>warning<\/em> yellow UAC dialog.<\/p>\n<h3>Executable File Properties<\/h3>\n<p>You can verify the digital signature in the Cradle installation files:<\/p>\n<figure id=\"attachment_936\" aria-describedby=\"caption-attachment-936\" style=\"width: 300px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-936 size-medium\" src=\"https:\/\/www.threesl.com\/blog\/wp-content\/uploads\/2017\/03\/View-Digital-Certificates-300x278.png\" alt=\"Cradle system engineering tool digital certificates\" width=\"300\" height=\"278\" srcset=\"https:\/\/www.threesl.com\/blog\/wp-content\/uploads\/2017\/03\/View-Digital-Certificates-300x278.png 300w, https:\/\/www.threesl.com\/blog\/wp-content\/uploads\/2017\/03\/View-Digital-Certificates.png 611w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-936\" class=\"wp-caption-text\">View Digital Certificates in Cradle Executables<\/figcaption><\/figure>\n<p>If the file does not contain a digital certificate, then you know that the file has been tampered with since 3SL created it, or it was not created by 3SL at all.<\/p>\n<h3>Information Assurance<\/h3>\n<p>The use of digital certificates is part of 3SL&#8217;s commitment to ensuring that Cradle contributes to the information assurance practices in your organisation.
