extractCerts

public static java.security.cert.X509Certificate[] extractCerts(java.lang.String certFilePath)
                                                         throws java.security.cert.CertificateException,
                                                                java.io.IOException

Retrieves certificates from PEM-encoded (ASCII) or DER-encoded (binary) file at the specified certFilePath.

Parameters:

certFilePath - the path of the file containing a certificate(s).

Returns:

a sequence of X509Certificate certificates found in the file.

Throws:

java.security.cert.CertificateException - if parsing of the certificate fails

java.io.IOException - if a file in not found at the specified certFilePath or some other IO error occurs.

java.lang.NullPointerException - if certFilePath is null

java.lang.IllegalArgumentException - if certFilePath is empty

toString

createTrustStore

public static java.security.KeyStore createTrustStore(java.lang.String certFilePath)
                                               throws java.security.cert.CertificateException,

Creates a truststore with certificates from PEM-encoded (ASCII) or DER-encoded (binary) file at the specified certFilePath.

Parameters:

certFilePath - the path of the file containing a certificate chain.

Returns:

a truststore loaded with the certificate chain present in the specified certFilePath

Throws:

java.security.cert.CertificateException - if parsing of the certificate fails

java.io.IOException - if a file in not found at the specified certFilePath, or some other IO error occurs

java.security.KeyStoreException - if creating an instance of the truststore fails for some reason.
