Enum KeyTemplate.OutputPrefixType

java.lang.Object

java.lang.Enum<KeyTemplate.OutputPrefixType>

com.google.crypto.tink.KeyTemplate.OutputPrefixType

All Implemented Interfaces:

Serializable, Comparable<KeyTemplate.OutputPrefixType>

Enclosing class:

KeyTemplate

public static enum KeyTemplate.OutputPrefixType
extends Enum<KeyTemplate.OutputPrefixType>

Tink produces and accepts ciphertexts or signatures that consist of a prefix and a payload. The payload and its format is determined entirely by the primitive, but the prefix has to be one of the following 4 types:

• Legacy: prefix is 5 bytes, starts with \x00 and followed by a 4-byte key id that is computed from the key material.
• Crunchy: prefix is 5 bytes, starts with \x00 and followed by a 4-byte key id that is generated randomly.
• Tink : prefix is 5 bytes, starts with \x01 and followed by 4-byte key id that is generated randomly.
• Raw : prefix is 0 byte, i.e., empty.

Method Detail

values

public static KeyTemplate.OutputPrefixType[] 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 (KeyTemplate.OutputPrefixType c : KeyTemplate.OutputPrefixType.values())
    System.out.println(c);

Returns:

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

valueOf

public static KeyTemplate.OutputPrefixType valueOf(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:

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

NullPointerException - if the argument is null
