java.lang.Enum<HashAlgorithm>

com.smartgwt.client.types.HashAlgorithm

All Implemented Interfaces:

ValueEnum, java.io.Serializable, java.lang.Comparable<HashAlgorithm>

public enum HashAlgorithm
extends java.lang.Enum<HashAlgorithm>
implements ValueEnum

Algorithms to use when hashing field values (see DataSourceField.storeWithHash). Note that the MD5 and SHA algorithms are deprecated as secure hashes since they are vulnerable to collisions created by an attacker with current technology, though they may still be useful in detecting corruption due to faulty transmission or storage.

Enum Constant Detail

MD5

public static final HashAlgorithm MD5

Message Digest algorithm. Deprecated as a secure hash.

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "MD5".

SHA

public static final HashAlgorithm SHA

Secure Hashing Algorithm (SHA-1). Deprecated as a secure hash.

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "SHA".

SHA_256

public static final HashAlgorithm SHA_256

Secure Hashing Algorithm (SHA-256).

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "SHA-256".

SHA_512

public static final HashAlgorithm SHA_512

Secure Hashing Algorithm (SHA-512).

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "SHA-512".

BCRYPT

public static final HashAlgorithm BCRYPT

bcrypt is a password hashing function designed by Niels Provos and David Mazieres, based on the Blowfish cipher.

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "bcrypt".

Method Detail

values

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

Returns:

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

valueOf

public static HashAlgorithm 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

getValue

public java.lang.String getValue()

Specified by:

getValue in interface ValueEnum
