MD2

This message digest algorithm produces a 128-bit digest. The algorithm is described in RFC-1319. This algorithm is provided for compatibility only and is not recommended for other purposes. Instances of this algorithm cannot be cloned.

To create a MD2 message digest for the message “hello world”:

MessageDigest md2 = MessageDigest.getInstance(“MD2”, “SAFENET”);
byte[] digest = md2.digest(“hello world”.getBytes());

MD5

This message digest algorithm produces a 128-bit digest. The algorithm is described in RFC-1321. This algorithm is provided for compatibility only and is not recommended for other purposes. Instances of this algorithm cannot be cloned.

To create a MD5 message digest for the message “hello world”:

MessageDigest md5 = MessageDigest.getInstance(“MD5”, “SAFENET”);
byte[] digest = md5.digest(“hello world”.getBytes());

SHA-1

The SHA-1 message digest algorithm produces a 160-bit digest. The algorithm is described in FIPS PUB 180-1. Instances of this algorithm cannot be cloned.

To create a SHA-1 message digest for the message “hello world”:

MessageDigest sha1 = MessageDigest.getInstance(“SHA-1”, “SAFENET”);
byte[] digest = sha1.digest(“hello world”.getBytes());

SHA-224

The SHA-224 message digest algorithm produces a 224-bit digest. The algorithm is described in FIPS PUB 180-1. Instances of this algorithm cannot be cloned.

To create a SHA-224 message digest for the message “hello world”:

MessageDigest sha256 = MessageDigest.getInstance(“SHA-224”, “SAFENET”);
byte[] digest = sha224.digest(“hello world”.getBytes());

SHA-256

The SHA-256 message digest algorithm produces a 256-bit digest. The algorithm is described in FIPS PUB 180-1. Instances of this algorithm cannot be cloned.

To create a SHA-256 message digest for the message “hello world”:

MessageDigest sha256 = MessageDigest.getInstance(“SHA-256”, “SAFENET”);
byte[] digest = sha256.digest(“hello world”.getBytes());

SHA-384

The SHA-384 message digest algorithm produces a 384-bit digest. The algorithm is described in FIPS PUB 180-1. Instances of this algorithm cannot be cloned.

To create a SHA-384 message digest for the message “hello world”:

MessageDigest sha384 = MessageDigest.getInstance(“SHA-384”, “SAFENET”);
byte[] digest = sha384.digest(“hello world”.getBytes());

SHA-512

The SHA-512 message digest algorithm produces a 512-bit digest. The algorithm is described in FIPS PUB 180-1. Instances of this algorithm cannot be cloned.

To create a SHA-512 message digest for the message “hello world”:

MessageDigest sha512 = MessageDigest.getInstance(“SHA-512”, “SAFENET”);
byte[] digest = sha512.digest(“hello world”.getBytes());

RIPEMD128

The RIPEMD128 message digest algorithm produces a 128-bit digest. Instances of this algorithm cannot be cloned.

To create a RIPEMD128 message digest for the message “hello world”:

MessageDigest rmd128 = MessageDigest.getInstance(“RIPEMD128”,
 “SAFENET”);
byte[] digest = rmd128.digest(“hello world”.getBytes());

RIPEMD160

The RIPEMD160 message digest algorithm produces a 160-bit digest. Instances of this algorithm cannot be cloned.

To create a RIPEMD160 message digest for the message “hello world”:

MessageDigest rmd160 = MessageDigest.getInstance(“RIPEMD160”,
 “SAFENET”);
byte[] digest = rmd160.digest(“hello world”.getBytes());
