Class Pem

java.lang.Object
com.codename1.backend.security.pki.Pem
public final class Pem extends Object

PEM, the base64 text form of DER that openssl reads and writes: one or more blocks between -----BEGIN <label>----- and -----END <label>-----.

List<Pem.Block> blocks = Pem.decode(fullChainPem);
String pem = Pem.encode(Pem.CERTIFICATE, certificate.getEncoded());

Text outside the blocks, such as the Bag Attributes lines openssl pkcs12 prints, is ignored. A block with RFC 1421 headers (an encrypted traditional key) is refused, since its content is not plain DER.
