Hi, Looking for a female Malayalam voice over Artist. Regards, aes.

First off, I'm not sure if my project request is possible. PLEASE review the following details before you place a bid. I have a small javascript project that works. The issue is that a portion of the script appears (to me) to have been encrypted. What I am seeking is for the script to work, without ANY encryption. I have attached the entire zipped project (3 files). Please note that the "encrypted" part, if that is what it is, begins on line 48 of the "" file. I will be available to respond to any questions. Thank you.

PLEASE APPLY IF YOU HAD PRIOR EXPERIENCE ON THIS. I am looking for someone to provide me a windows command to encrypt and decrypt a windows file using Gpg4win . should use a password to encrypt/decrypt the file.

I have a website that use wordpress, actually the client upload a file in json or excel via an ftp and with a script it import the information to a database under PHP myadmin in WordPress or with a cron we have a export every 5 mins json or excel depend on the script we are using. But we are looking to secure the procedure where the client upload the file as a pgp then we use a script to extract it to json or excel so that our script can import it to the database and same for export, our script export the file in a folder then we concert it in pgp. We use Cpanel environement Please note that we have two type of script it either json or excel.

Hello everyone! I’m looking for a way to move a score from RenPy to a webserver using an URL, but in order players not to change it, it has to go encoded. So, the idea is to create a mathematical encryption in Ren'Py so when the player gets a score, the game makes something like this: $ player_score = 250 $ key = (10,99) … do something … $ player_score_encrypted = player_score * key imagebutton auto .... action OpenURL(""+key+"&score="+player_score_encrypted) Then on the server side using PHP: $player_score_encrypted = (isset($_GET['score'])) ? $_GET['score'] : 0; $key = (isset($_GET['key'])) ? $_GET['key'] : 0; $player_score = $ player_score_encrypted / $key; Obviously, this is way to s...

A reserving room before encryption framework is proposed to provide separable reversible data hiding for encrypted images in this project. An Adaptive grayscale image coding scheme based on dynamic multi-grouping absolute moment block truncation coding (MGAMBTC) is used to enhance the hiding capacity. A receiver with only the hiding key can extract the secret data without knowing about the content. If the receiver has only the encryption key, it is not possible to extract the hidden secret data, but it is possible to decrypt an image similar to the original image. Only when the receiver has both the hiding key and the encryption key, it is possible to extract the secret data and completely recover the original content without any error. The experimental results demons...

Meta Data Partition: This is a partition that is only visible to the controller to store data/metadata like pin, encryption keys etc. o Every read & write operation destined for Pp1 & Pp2 partitions should automatically be encrypted/decrypted via the controller (encryption algorithm can be simply Xoring the data). o The key for encryption/decryption & both PINs should be changeable in Meta Data Partition. o IOCTLS should be used to mark any partition as PP1 or PP2 o Once the partition is visible to the host/machine (after authentication) it will behave like normal volumes ...

Greetings.. i am looking for top notch JavaScript expert who can debug (get actual code) from obfuscated/minified JavaScript code/files. And also you must have experience using developer tools in browser to pin point the required file/codes.

..."","(key)"); decrypt("", "","(key)"); } File encryption must be implemented using the following libraries: Salsa20 HC-256 SOSEMANUK The source code there is written in C, but it can be plugged into c++ and compiled into one file. It also needs optimization of RAM, and the correct read/write file, so that the memory is freed after the encryption of the file. Write code and test it strictly on Linux, because RAM on windows and linux in c++ is optimized differently. Also for clarity, there is an example of file encryption using An example can be found in the

Hi Vishal S., you've done some research for me in the past and I was wondering whether you would be interested in doing something almost identical again (just for a different industry)? I need a list of merger and acquisition plus fundraising transactions involving data encryption companies over the last three years. What was the size of the acquired party in terms and revenue and employees, and what was their valuation on sale or merger or fundraise? Lett me know if you would be up for doing this. Neill

Hi, i have a bootstrap panel which gives a multi-layer encryption output. I am looking to have the final layer of the output encryption removed. The final layer is AES.

For the implementation & comparison, we have selected the algorithms DES, 3DES, AES, Blowfish & RSA. For comparison, we have used files of different sizes like 25 KB, 50 KB, 1 MB, 2 MB, and 3 MB. The same input files are used for all encryption algorithms. For evaluation of the performance of various encryption algorithms, the following metrics have been chosen. Encryption time, Decryption time, Avalanche effect, Memory consumption WE REQUIRE ANY PROGRAMMING LANGUAGE CODE IMPLEMENTATION OF THESE ALGORITHMS TO COMPARE THE ABOVE-MENTIONED PARAMETERS.

Action: In this step, you will implement your own encryption code. You may use a programming language of your choice. Then, you will need to choose a cryptographic library. Then, you will choose an appropriate encryption algorithm. Alternatively, you may a cryptographic utility, and write a shell code. : In this step, you need to implement a method for infecting a victim. Example: A victim may open a phishing email which contains a malicious executable/script as an attachment. 3. Monitoring: To be able to detect a ransomware, we need to be able to monitor your environment. Example: OSSEC Host IDS has a file integrity monitoring functionality. Provide your own detection component 4. Detection: In this stage, you will analyze the data collected by the monitoring co...

...Also the speed of encryption will be very important, namely because of speed I chose stream algorithm instead of block algorithm. I work with transmitting important files over unsecured channels on a regular basis, at the moment I used and use the usual openssl aes-128-cbc, but the encryption speed leaves much to be desired... Therefore, I need a stable utility, but for Salsa20/SOSEMANUK and that quickly encrypted files that weigh from 1kb up to 50kb +. I would like to see it work in the following variants: 1) Sources c++ which can be compiled into usable variant ELF for linux, so it could be put to /bin folder and used as console openssl, extended fileencryptor -enc -in / -out / -key (256bit key) 2) C++ source code, where file encryption is implemented b...

...is much more open to security assaults in the 21st century than it was in the past. Homomorphic encryption, for example, is used to maintain the security and privacy of data in the cloud since it offers greater dependability than other solutions. Despite the fact that Fully Homomorphic Encryption offers improved privacy and security, there are a number of challenges with key management and storage. Therefore, to overcome this drawback homomorphic encryption can be infused with the PSO (Particle Swarm Optimization) algorithm to achieve effective key management. The main motive of the project is to enhance the key generation, sharing, and management process which is done using Homomorphic encryption with the help of the PSO Algorithm. Moreover, Diffe Helman ca...
