SigTools is a command-line utility for converting a certificate into a byte array. Supported inputs are Android
.apk app files or those formatted according to Distinguished Encoding Rules (DER), which generally contain an X.509 binary certificate used for secure websites. Output is formatted as a Java class, a hexadecimal string, a base64 encoded string or a DER file and also is copied to the host-system clipboard. Optionally, the output can be written to a file.
The HEX or DER output forms of this utility can be used to create a signature file for securing apps using the Zebra Access Manager CSP.
.apk file(s) from which to extract the signature(s)
Zebra does not recommend using this utility for production environments. This app is an example of how to extract and generate a signature file from an app. No Zebra support or warranty is expressed or implied.
