The Cryptographic Message Syntax (CMS) is the IETF's standard for cryptographically protected messages. It can be used by cryptographic schemes and protocols to digitally sign, digest, authenticate or encrypt any form of digital data. CMS is based on the syntax of PKCS #7, which in turn is based on … See more • CAdES - CMS Advanced Electronic Signatures • S/MIME • PKCS #7 See more • RFC 8933 (Update to the Cryptographic Message Syntax (CMS) for Algorithm Identifier Protection) • RFC 5652 (Cryptographic Message Syntax (CMS), in use) • RFC 3852 (Cryptographic Message Syntax (CMS), obsolete) See more WebThe Protect-CmsMessage cmdlet encrypts content by using the Cryptographic Message Syntax (CMS) format. The CMS cmdlets support encryption and decryption of content using the IETF format as documented by RFC5652. The CMS encryption standard uses public key cryptography, where the keys used to encrypt content (the public key) and the keys used …

WebIf the message preparer is able to find cryptographic hash function collisions (i.e., two messages producing the same hash value), then they might prepare meaningful versions of the message that would produce the same hash value and digital signature, but with different results (e.g., transferring $1,000,000 to an account, rather than $10). WebThe Cryptographic Message Syntax (CMS) [ RFC5652] can be used to digitally sign, digest, authenticate, or further encrypt this content type.
