Category: Software Development
Job Description: The signatures on the Users sheet are signed manually by users before they add their signature as reviewer or auditor. We need the following few python functions that can validate the various signatures on the Users sheet. Please include a script that will test the functions.

validate_enrollment(enrollment_signature_text) - validates the ECDSA signature on the Enrollment signature as valid/invalid. also checks that it was signed by the master signing key within.
Returns an array with:
* true/false bool that signature verifies and uses specified master signing key
* signing key

validate_review(reviewer_text) - checks the outer signature on a review.
Returns an array with:
* true/false on the signature verification
* signing address
* text of message that was signed (everything between ----BEGIN BITCOIN SIGNED MESSAGE----- and ----BEGIN SIGNATURE-----) with the dash-space removed from the beginning of the internal ----- lines. This should enable the message to be verified by validate_enrollment.
 
validate_audit(auditor_text) - checks the outer signature on an audit
Returns an array with:
* true/false on the signature verification
* signing address
* text of message that was signed (everything between ----BEGIN BITCOIN SIGNED MESSAGE---- and ----BEGIN SIGNATURE----) with the dash-space removed from the beginning of the ----- lines for ONLY the outermost signature. This should enable the message to be verified by validate_review.

Please PM weex on bitcointalk.org with any questions.
