iOS TrustMe

An extreme method of disabling most certificate verification checks within iOS applications. TrustMe will defeat certificate pinning in most cases.


Requires a jailbroken device. This "Tweak" disables the SecTrustEvaluate. It should only be used on testing devices with no personal data or information, since this will completely disable most SSL safeguards.


  • MobileSubstrate (Should come with jailbroken devices)
  • dpkg (Install from Cydia)


Download the dpkg

wget https://www.dropbox.com/s/zyltyoa7s1x3m47/com.intrepidusgroup.trustme_0.1-4_iphoneos-arm.deb

dpkg -i com.intrepidusgroup.trustme_0.1-4_iphoneos-arm.deb


To disable it, uninstall the deb:

dpkg -r com.intrepidusgroup.trustme

Alternately, you can edit the plist located at /Library/MobileSubstrate/DynamicLibraries/trustme.plist

Documentation on the format of the plist can be found at



Building requires theos.


This is a Theos 'tweak' project. Use theos to create the required files and then run:



This tool is patterned on ios-ssl-kill-switch (https://github.com/iSECPartners/ios-ssl-kill-switch). Trustme uses a similar technique, but targets a C function that is lower in the call chain of most SSL certificate validation code, which allows it to disable more SSL validation code.
