public class SecretOctetString
extends OctetString

The SecretOctetString is an OctetString for secret data like keys and passwords. It behaves like a regular OctetString except that the toString() method does not reveal any security information but returns a AuthHMAC192SHA256 hash of the real security information.

public SecretOctetString(OctetString secret)

SecretOctetString

public SecretOctetString(byte[] rawValue)

SecretOctetString

public SecretOctetString(byte[] rawValue,
 int offset,
 int length)

Creates an octet string from an byte array.

Parameters:

rawValue - an array of bytes.

offset - the position (zero based) of the first byte to be copied from rawValueinto the new OctetString.

length - the number of bytes to be copied.

public SecretOctetString()

Method Details

fromOctetString

public static SecretOctetString fromOctetString(OctetString octetString)

Create a SecretOctetString from a OctetString but return null if the given OctetString is null.

Parameters:

octetString - an OctetString whose to*String methods needs to be protected against disclosing sensitive information.

Returns:

the new SecretOctetString or null.

toString

public String toString()

Description copied from class: OctetString

Returns a String representation of this OctetString. If the OctetString contains non-printable characters, a hex-string representation is returned unless SNMP4JSettings.getDefaultNonPrintableEscapeCharacter() returns a non-null character that is then used to replace all non-printable characters in the output.

Specified by:

toString in interface Variable

Overrides:

toString in class OctetString

Returns:

a String representation of this OctetString.

toHexString

public String toHexString()

Overrides:

toHexString in class OctetString

toHexString

public String toHexString(char separator)

Overrides:

toHexString in class OctetString

toString

public String toString(char separator,
 int radix)

Overrides:

toString in class OctetString

toString

public String toString(int radix)

Description copied from class: OctetString

Returns a string representation of this octet string in the radix specified. There will be no separation characters, but each byte will be represented by round(log(256)/log(radix)) digits.

Overrides:

toString in class OctetString

Parameters:

radix - the radix to use in the string representation.

Returns:

a string representation of this ocetet string in the specified radix.
