pem-utils

A small Java library for reading PEM-encoded DER files of various types.

Building

$ mvn package

Usage

Quick and Simple

import net.christopherschultz.pemutils.PEMFile;
.
.
.
Collection<PEMFile.Entry> entries = PEMFile.decode(_string or stream_);
for(PEMFile.Entry entry : entries) {
    if(entry instanceof PEMFile.CertificateEntry) {
        System.out.println("This is a certificate: " + ((PEMFile.CertificateEntry)entry).getCertificate());
    } else if(entry instanceof PEMFile.PrivateKeyEntry) {
        System.out.println("This is a private key of type " + ((PEMFile.PrivateKeyEntry)entry).getAlgorithm());
    }
}

Somewhat more involved...

import net.christopherschultz.pemutils.PEMFile;
.
.
.
PEMFile pm = new PEMFile(_string or stream_);
PEMFile.Entry entry;
while(null != (entry = pm.getNext())) {
  // Do whatever with the entry
}
