Solaris 10 What's New

Signing ELF Objects

This feature is new in the Solaris 10 3/05 release.

The libraries and executable files in the Solaris 10 OS include digital signatures that can be used to verify the integrity of these files. The digital signature provides a way to detect any accidental change or deliberate tampering with the executable content of the file.

Plug-ins for the Solaris Cryptographic Framework are automatically verified when loaded by the system. The elfsign command can be used manually to verify any signed file. Developers and administrators can also use elfsign to sign their own code.

For further information, see the elfsign(1) man page.
