Method Detail

parse

public static X509Certificate parse(byte[] derEncodedCert)

Parses a DER-encoded X.509 certificate.

Parameters:

derEncodedCert - The DER-encoded X.509 certificate, as a byte array. May be null.

Returns:

The X.509 certificate, null if parsing failed.

parse

public static X509Certificate parse(String pemEncodedCert)

Parses a PEM-encoded X.509 certificate.

Parameters:

pemEncodedCert - The PEM-encoded X.509 certificate, as a string. May be null.

Returns:

The X.509 certificate, null if parsing failed.

toPEMString

public static String toPEMString(X509Certificate cert)

Returns the specified X.509 certificate as PEM-encoded string.

Parameters:

cert - The X.509 certificate. Must not be null.

Returns:

The PEM-encoded X.509 certificate, null if encoding failed.

toPEMString

public static String toPEMString(X509Certificate cert,
                                 boolean withLineBreaks)

Returns the specified X.509 certificate as PEM-encoded string.

Parameters:

cert - The X.509 certificate. Must not be null.

withLineBreaks - false to suppress line breaks.

Returns:

The PEM-encoded X.509 certificate, null if encoding failed.

computeSHA256Thumbprint

public static Base64URL computeSHA256Thumbprint(X509Certificate cert)

Computes the X.509 certificate SHA-256 thumbprint (x5t#S256).

Parameters:

cert - The X.509 certificate. Must not be null.

Returns:

The SHA-256 thumbprint, BASE64URL-encoded, null if a certificate encoding exception is encountered.
