Class PEMFileKeyManager

java.lang.Object

com.unboundid.util.ssl.PEMFileKeyManager

All Implemented Interfaces:

java.io.Serializable, javax.net.ssl.KeyManager, javax.net.ssl.X509KeyManager

@NotMutable
@ThreadSafety(level=COMPLETELY_THREADSAFE)
public final class PEMFileKeyManager
extends java.lang.Object
implements javax.net.ssl.X509KeyManager, java.io.Serializable

This class provides an implementation of an X.509 key manager that can obtain a certificate chain and private key from PEM files. This key manager will only support a single entry, and the alias for that entry will be a SHA-256 fingerprint for the certificate. However, the certificate can be retrieved with any (or no) alias.

PEMFileKeyManager

public PEMFileKeyManager(@NotNull
                 java.io.File certificateChainPEMFile,
                 @NotNull
                 java.io.File privateKeyPEMFile)
                  throws java.security.KeyStoreException

Creates a new instance of this key manager with the provided PEM files.

Parameters:

certificateChainPEMFile - The file containing the PEM-formatted X.509 representations of the certificates in the certificate chain. This must not be null, the file must exist, and it must contain at least one certificate (the end entity certificate), but may contain additional certificates as needed for the complete certificate chain. Certificates should be ordered such that the first certificate must be the end entity certificate, and each subsequent certificate must be the issuer for the previous certificate. The chain does not need to be complete as long as the peer may be expected to have prior knowledge of any missing issuer certificates.

privateKeyPEMFile - The file containing the PEM-formatted PKCS #8 representation of the private key for the end entity certificate. This must not be null, the file must exist, and it must contain exactly one PEM-encoded private key.

Throws:

java.security.KeyStoreException - If there is a problem with any of the provided PEM files.

PEMFileKeyManager

                  throws java.security.KeyStoreException

Creates a new instance of this key manager with the provided PEM files.

Parameters:

certificateChainPEMFiles - The files containing the PEM-formatted X.509 representations of the certificates in the certificate chain. This must not be null or empty. Each file must exist and must contain at least one certificate. The files will be processed in the order in which they are provided. The first certificate in the first file must be the end entity certificate, and each subsequent certificate must be the issuer for the previous certificate. The chain does not need to be complete as long as the peer may be expected to have prior knowledge of any missing issuer certificates.

privateKeyPEMFile - The file containing the PEM-formatted PKCS #8 representation of the private key for the end entity certificate. This must not be null, the file must exist, and it must contain exactly one PEM-encoded private key.

Throws:

java.security.KeyStoreException - If there is a problem with any of the provided PEM files.

Parameters:
