Cryptographic Message Syntax (CMS)

Cryptographic Message Syntax (CMS) is a standard format used to securely encode and protect digital messages. It ensures confidentiality through encryption, verifies the sender's identity via digital signatures, and maintains message integrity. CMS is widely used in securing emails, documents, and other data, providing a structured way to combine encryption, signing, and other cryptographic features into a single, organized format. This standard helps different software and systems reliably exchange protected information while maintaining security and trust.
