“…In addition to the ever-expanding stamping family, many of the functions of digital stamps are also used with conventional stamps (Alharbi & Abdullah, 2019), (MacCormick, 2011), (B. Thigale et al, 2019, (N. Mohammed et al, 2019).…”

The current study's objectives are to analyze a broad overview of hash function applications in cryptography and investigate the connections between digital signature applications and cryptographic hash functions. Applications of the hash function are widespread and used for a variety of purposes, including password hashing, file integrity verification, key derivation, time stamping, rootkit detection, and digital signatures. Cryptographic hash functions are a crucial tool used in many sections of data security. A digital signature is a code that is electronically associated with a document and includes the sender's information. As a result, the usefulness of the digital signature in validating digital messages or documents is great. Without mathematics, there would be no cryptographic hash functions. Mathematics is credited with computer science's success, or, to put it another way, it is because of mathematical science that computer science is understood and can be explained to everyone. The study's main goals are to explain hash functions to the reader, as well as some of their uses, including digital signatures, and to provide detailed examples of some hash functions and their creation. Keywords: Hash Function, Cryptography, Digital Stamping

The authentication, identification, and copyright protection can be obtained by constructing the digital image watermarking technique. Watermark robustness and imperceptibility account for the capability of the hidden watermark to survive the manipulation. The proposed paper is a robust algorithm for digital image watermarking with 3-level discrete wavelet transform (DWT) with some attacks method. The 3-level DWT method was used constants α=0.01 and 0.03 as a function of how depth the watermark inserts to the host image in the insertion and extraction process. The algorithm was evaluated using 8 bits per pixel (bpp) grayscale, 1024x1024 pixels for the host image, and 256x256 pixels for the watermark image. The method is also implemented some experimental with attacks such as gaussian, salt and pepper, blurring, and compression. The algorithm is relatively acceptable of good quality, achieves low-value mean squared error (MSE), high peak signals to noise ratio (PSNR), and structural similarity index metric (SSIM) value approach to 1. It is found that the highest image quality measurements by using α=0.03 with the attacking method of salt and pepper yield MSE=0.01, PSNR=45.6 dB and SSIM=0.95, respectively.
