This standard describes a keyed-hash message authentication code (HMAC), a mechanism for message authentication using cryptographic hash functions. HMAC can be used with any iterative Approved cryptographic hash function, in combination with a shared secret key. The cryptographic strength of HMAC depends on the properties of the underlying hash function. The HMAC specification in this standard is a generalization of Internet RFC 2104, HMAC, Keyed-Hashing for Message Authentication, and ANSI X9.71, Keyed Hash Message Authentication Code.

This m file hide an image jpeg,png in another jpeg,png image. The height and width of the secret image is in LSB of 1st 32 pixels of 1st row of the cover image.This helps in the recovery of secret image. The secret image must be smaller than cover image.A message box will appear with a number ,that number is the maximum product of width and height of secret image that can be successfully embedded in the cover image. The final png image will appear in workspace with random name.This image contains the secret image.One such png image is in the zip file with name 4447.png it contains an image of res 100x122.

a true random number generator (TRNG) in hardware which is targeted for FPGA-based crypto embedded systems. All crypto protocols require the generation and use of secret values that must be unknown to attackers.Random number generators (RNG) are required to generate public/private key pairs for asymmetric algorithm such as RSA and symmetric algorithm such as AES.
