Hi, im receiving the above error when trying to read the private key from apple.

i converted the p8 file from apple using

openssl pkcs8 -nocrypt -in AuthKey_4SND569782.p8 -out AuthKeyNEW.pem

When running the code i get:

java.io.IOException: Could not find private key header/footer
        at com.eatthepath.pushy.apns.auth.ApnsSigningKey.loadFromInputStream(ApnsSigningKey.java:151)

Well, if we take a look at ApnsSigningKey#loadFromInputStream, we can see that this exception gets thrown if we can't find a line that contains "BEGIN PRIVATE KEY" and a lone that contains "END PRIVATE KEY":

pushy/pushy/src/main/java/com/eatthepath/pushy/apns/auth/ApnsSigningKey.java

Lines 135 to 152 in da5f8b9

for (String line; (line = reader.readLine()) != null; ) {
if (!haveReadHeader) {
if (line.contains("BEGIN PRIVATE KEY")) {
haveReadHeader = true;
}
} else {
if (line.contains("END PRIVATE KEY")) {
haveReadFooter = true;
break;
} else {
privateKeyBuilder.append(line);
}
}
}
if (!(haveReadHeader && haveReadFooter)) {
throw new IOException("Could not find private key header/footer");
}

If you look at your key file, do you see those lines? Also, I'm a little surprised your initial .p8 file isn't already in the expected format. Are you sure you need to use openssl to convert it to a PEM file?
