WordPad

Microsoft

WordPad is a basic text-editing app you can use to create and edit files, include text with different fonts and colors, insert pictures, and add links to other files. You can use WordPad to open and save text files (.txt), rich text files (.rtf), Word documents (.docx), and OpenDocument text files (.odt). Files in other formats will open as plain text files and might not appear as expected. Some features, like headers, footers, and annotations, aren’t supported in WordPad. If you open a file with these features and then save the file in WordPad, you’ll lose the content in these features. If you want to change such a file, but don’t want to lose the original content, tap or click Save as and save the file with a different name. That way you can make changes to a copy of the file while keeping the content in the original file intact. For more info about what each button does, press and hold the button for a description (or if you’re using a mouse, point to the button).

Contrast Security

Modern software development must match the speed of the business. But the modern AppSec tool soup lacks integration and creates complexity that slows software development life cycles. Contrast simplifies the complexity that impedes today’s development teams. Legacy AppSec employs a one-size-fits-all vulnerability detection and remediation approach that is inefficient and costly. Contrast automatically applies the best analysis and remediation technique, dramatically improving efficiencies and efficacy. Separate AppSec tools create silos that obfuscate the gathering of actionable intelligence across the application attack surface. Contrast delivers centralized observability that is critical to managing risks and capitalizing on operational efﬁciencies, both for security and development teams. Contrast Scan is pipeline native and delivers the speed, accuracy, and integration demanded by modern software development.
