Class MessageDigestImpl

java.lang.Object

java.security.MessageDigestSpi

com.fortanix.sdkms.jce.provider.digests.MessageDigestImpl

Direct Known Subclasses:

MessageDigestImpl.SHA1MessageDigest, MessageDigestImpl.SHA256MessageDigest, MessageDigestImpl.SHA384MessageDigest, MessageDigestImpl.SHA512MessageDigest, MessageDigestImpl.Streebog256MessageDigest, MessageDigestImpl.Streebog512MessageDigest

public abstract class MessageDigestImpl
extends MessageDigestSpi

This MessageDigestImpl class provides applications the functionality of a message digest algorithm, such as SHA-1 or SHA-256. Message digests are secure one-way hash functions that take arbitrary-sized data and output a fixed-length hash value.

Every implementation of the Java platform is required to support the following standard MessageDigestImpl algorithms:

• SHA-1
• SHA-256
• SHA-384
• SHA-512
