I am running the below code to open a p12 file and convert it's
certificates to x509. For the linked p12 file, I get the below exception
(have tried on multiple android OS builds). This conversion works properly
when I run similar Java code. Also, on desktop applications like Internet
explorer, and I can convert it's certificates to x509.
Is due to java.security implementation on Android, or is my code incorrect?
java.security.cert.CertificateException:
org.apache.harmony.security.asn1.ASN1Exception: ASN.1 boolean: wrong
content at [4]. DER allows only 0x00 or 0xFF values
