There are various uses of MD5 Algorithm are as follows −MD5 stands for Message-Digest algorithm 5. It is a broadly used cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been used in a broad method of security applications, and is also generally ... Read More

MD5 stands for message-digest algorithm. It is a cryptographic protocol used for authenticating messages as well as content verification and digital signatures. MD5 is based on a hash function that checks that a file it can sent matches and the file received by the person that it is sent to.MD5 ... Read More

MACMAC stands for Message Authentication Code. It is also defined as a tag. It can be used to authenticate the origin and characteristics of a message. MACs need authentication cryptography to check the legitimacy of information sent through a network or moved from one person to another.A MAC is created ... Read More

SteganographySteganography is the procedure of hiding data, images, or audio messages within another element of information, image, or audio. Steganography is the art of hiding data.In computer science, it can define hiding information within a message or file. It serves a similar objective to cryptography, but rather than encrypting information, ... Read More

MAC stands for Message Authentication Code. It is a security code or tag that is further to the message sent by the sender to the receiver for supporting message authentication and integrity (no modification in message).MAC is similar to Message Digest (MD) except that it needs the symmetric key cryptography ...

Steganography is an approach that simplify hiding of a message that is to be maintain secret within other message. This result is the secrecy of the hidden message itself. Steganography approach can be used to images, a video file or an audio file.The use of steganography such as watermarking which ... Read More

HMAC stands for Keyed-Hashing for Message Authentication. It is a message authentication code acquired by running a cryptographic hash function (such as MD5, SHA1, and SHA256) over the information (to be authenticated) and a shared secret key. HMAC is defined in RFC 2104.HMACs are same as digital signatures. They both ... Read More

The main goals of frequency domain watermarking is to embed the watermarks in the spectral coefficients of the image. The most generally used transforms are the Discrete Cosine Transform (DCT), Discrete Fourier Transform (DFT), and Discrete Wavelet Transform (DWT).The main reason for watermarking in the frequency domain is that the ...

The spatial domain define the image in the form of pixels. The spatial domain watermarking embeds the watermark by changing the intensity and the colour value of some preferred pixels.The spatial domain watermarking is simpler and its calculating speed is high than transform domain but it is less powerful against ...

A message authentication code is a block of a few bytes that can be used to authenticate a message. The receiver can test this block and be definite that the message hasn't been changed by the third party.A family of cryptographic functions that is parameterized by a symmetric key. Each ...
