Your screenshot shows part of a digital signature on a configuration profile. The signature uses the PKCS #7: Cryptographic Message Syntax format, often called CMS. There are various tools to view details of the signature. Here's a couple example command line tools available in macOS.
To view the certificate chain used to sign a configuration profile named profile.mobileconfig:
MessageSecurityTool -v decode -V -l CMSDecoder -i profile.mobileconfig
To view the signed data:
security cms -D -i profile.mobileconfig
Configuration profiles like the one you mentioned are signed for a few different reasons. The device will only install configuration profiles that contain certain payload types if it has a valid signature by a specific Apple certificate chain. Since only Apple has access to the private keys necessary to generate such a signature, it ensures that the configuration profile was generated by Apple. Also, the signature ensures that the profile cannot be modified, since changing even a single bit of the signed data invalidates the signature.
For more information about configuration profiles, see this documentation.
