protected static byte[]	chunkedBase64(byte[] data)	Encodes data as MIME Base64 (76-character lines separated by CRLF) with a trailing CRLF, matching the historical commons-codec Base64.encodeBase64(data, true) byte-for-byte so PEM-style blocks in the letter keep the -----END CERTIFICATE----- marker on its own line.
protected byte[]	getHash(byte[] certificate)	Returns the SHA-256 hash of the DER-encoded certificate.
protected String	getString(String key)	Returns the value of the property key.
void	writeTo(OutputStream output)	Saves the InitLetter to the given output stream.
