Enum Constant Detail

Z

public static final KeyScheme Z

Encryption of a single length DES key using X9.17 methods.

Used for encryption of keys under a variant LMK..

X

public static final KeyScheme X

Encryption of a double length key using X9.17 methods.

U

public static final KeyScheme U

Encryption of a double length DES key using the variant method.

Used for encryption of keys under a variant LMK.

Y

public static final KeyScheme Y

Encryption of a triple length key using X9.17 methods.

T

public static final KeyScheme T

Encryption of a triple length DES key using the variant method.

Used for encryption of keys under a variant LMK.

R

public static final KeyScheme R

Encryption of single/double/triple-length DES & AES keys using the ANSI X9 TR-31 Key Block methods.

Only used for exporting keys (e.g. under a KEK).

The ANSI X9 Committee published Technical Report 31 (TR-31) on Interoperable Secure Key ExcKey Block Specification for Symmetric Algorithms in 2010 to describe a method for secure key exchange which meets the needs of X9.24.

S

public static final KeyScheme S

Encryption of all DES, AES, HMAC & RSA keys using proprietary Key Block methods.

Used for encrypting keys for local use (under a Key Block LMK) or for importing/exporting keys (e.g. under a KEK or ZMK).

Method Detail

values

public static KeyScheme[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (KeyScheme c : KeyScheme.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static KeyScheme valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
