Method Details

logPeerCertificateInfo

public static void logPeerCertificateInfo(SSLSession session)

Log details on peer certificate and certification chain.

The log level is debug. Common X509 extensions are displayed in a best-effort fashion, a hexadecimal dump is made for less commonly used extensions.

Parameters:

session - the SSLSession to extract the certificates from

peerCertificateInfo

public static String peerCertificateInfo(Certificate certificate,
 String prefix)

Get a string representation of certificate info.

Parameters:

certificate - the certificate to analyze

prefix - the line prefix

Returns:

information about the certificate

extensionPrettyPrint

public static String extensionPrettyPrint(String oid,
 byte[] derOctetString,
 X509Certificate certificate)

Human-readable representation of an X509 certificate extension.

Common extensions are supported in a best-effort fashion, less commonly used extensions are displayed as an hexadecimal dump.

Extensions come encoded as a DER Octet String, which itself can contain other DER-encoded objects, making a comprehensive support in this utility impossible.

Parameters:

oid - extension OID

derOctetString - the extension value as a DER octet string

certificate - the certificate

Returns:

the OID and the value

stripCRLF

public static String stripCRLF(String value)

Strips carriage return (CR) and line feed (LF) characters to mitigate CWE-117.

Returns:

sanitised string value
