Imports
java.util.Objects, jdk.internal.util.Preconditions, jdk.internal.vm.annotation.IntrinsicCandidate
The MD5 class is used to compute an MD5 message digest over a given buffer of bytes. It is an implementation of the RSA Data Security Inc MD5 algorithm as described in internet RFC 1321.

pack-priv void
implCompress(byte[] buf, int ofs)

Implements abstract sun.security.provider.DigestBase.implCompress.

This is where the functions come together as the generic MD5 transformation operation.

pack-priv void
implCompress0(byte[] buf, int ofs)

private void
implCompressCheck(byte[] buf, int ofs)

pack-priv void
implDigest(byte[] out, int ofs)

Implements abstract sun.security.provider.DigestBase.implDigest.

Perform the final computations, any buffered bytes are added to the digest, the count is added to the digest, and the resulting digest is stored.

pack-priv void
implReset()

Implements abstract sun.security.provider.DigestBase.implReset.

Reset the state of this object.
