Hello to FreeLancer Coders, I have an Expert Advisor File (EA) and it's extension .ex4 , this file is an expert advisor that work on Meta Trader 4. This EA is Locked & Encrypted so i can't use it anymore and i really need someone who has Good experience in this field. Again Only Coders who have Good knowledge on how to UNLOCK & DECRYPT .ex4 files and EA files can bid on my post. i don't need someone who just don't know what is EA and .ex4 and don't know how to Unlock this file. This job is so small and don't need too much time of work for the one who know how to do it correctly & professionally. WHO should BID here should define how much time it needs to unlock the file and NOTE (I have to try first the EA file and see the source code and...
we are converting a mining pool from bitcoin to zcash it looks like the script is failing at decryption of the address. In the stratum-mining/lib/ script. If some would be willing to help debug this issue and possibly fix the decryption of the address that would be fantastic. BTC or ZEC reward on top of payment will be appointed upon success.
Hi, I have a project in class where I have to find someones password to enter in their Excel file. They gave me their N and E, their message and now I have to decrypt that message because that is their password.
Need someone to bugfix a secure ...implemented, the app itself is working fine, till encryption was implemented, the message gets encrypted, BUT receiving phone is not able to decrypt, so the job is to find the bug and fix it as fast as possible, this should be a simple task for the right guy. Additional information: Public key is used for encryption and private keys used for decryption. besides public and private keys: The sender of a message enters a key, same key must be used for decryption, i imagine that's the problem, but i dont know. The Application is programmed in android studio. A freelancer already wasted over a month of my time on this, so must be fixed FAST, so please if you can not start straight away or dont have the skills to do this, simply D...

Basically I need someone to do a builder using either C++, C#, .NET, or Python to build a microsoft macro The builder's options are: 1. Select a binary (exe) 2. Select encoding schemes (ASCII, Hex, Base64) 3. Select the location where to drop the exe after recompile it 4. Build option to build the macro in a text file ready to be pasted inside a word macro Basically the idea of the vbscript is to encode the binary into the encoding schemes mentioned stored to a variable, then decode the encoding to binary and store it to a different variable. Use the stored binary variable to write the content of the variable to the machine in which to run the macro in and run it in hidden format (vbHidden) Thanks

Looking for someone to write a library for CodeSys v3 (e!cockpit in WAGO). I need two functions. One to encrypt and second to decrypt STRING(512) variable with use of AES-256 method. Output variable shall be STRING(256) as well. Encryption Key shall be STRING type Used language suppose to be ST with use of libraries available in WAGO e!cockpit. Project is about to convert existing program written in C language to ST language - with use of only standard libraries so it can be imported into WAGO e!cockpit or CoDeSys 2.3. Example of source code to be converted can be found on Project has been partially converted (can send project to interested engineer).
Look at the solution of this post: I want to use this function with base64-encoded images of type JPG, PNG, GIF like this: newBase64 = resizeBase64Img(oldBase64, 100, 100); Note: My example does not work >> I need such a function which returns the resized image as base64 (or sets the value of newBase64 using a callback or whatever). I will choose a freelancer in about 12 hours when I'm back in office.

...ticketing and invoicing, but is weak regarding timesheets. I currently use a web-based tool called Toggl for timesheeting. Toggl has an API, and I have some VBA code that automatically creates customers and projects in Toggl from Excel. It's pretty simple code, which you can see in the attached screenshot (that's all of the code, minus a helper class to handle JSON encoding, and another to handle base64 encoding, neither of which we'll need to worry about in PHP). I'm after someone to implement the same code in Perfex. Ie: * Given a client ID and name in Perfex, you need to add a function to create that client in Toggl. Your function should return the Toggl client ID and save it to the Perfex database. * Given a project ID, project name, and client ID in ...
I want someone to design a Microsoft Macro that basically runs an executable which is included in the Macro as either Hex or ASCII or even base64 and run it.
I need someone who can solve this problem: Your job: Create an example-page which: 1. Encodes an image into a base64-string 2. Then a JavaScript-Function decodes the base64-string into binary data 3. Then it sends this binary data to a PHP-Script using $.post(....) 4. Then the PHP-Script saves the image as a file on the server
Write two computer programs to simulate an Unicode stream cipher that consists of both encryption and decryption algorithms. The encryption program accepts inputs from an existing text file, called “letter.txt.” The encryption program produces an output ciphertext file, called “secret” The decryption program takes “secret” as input and decrypts it into a plaintext, called “message.txt.” (Hint: the random “seed” must be known, but be kept secure, by the pseudorandom number generators in both encryption and decryption programs.) The program must run on java 6 and in command prompt/terminal

Dear Bumeen, We are need your help to fix some small issues in the core of our website and integrate the encryption library in...“encrypted encryption key” c. When user download a file, we will to send back the “encrypted encryption key” to their browser, then decrypt it with their plain password => so we have the “decryption key” or the plain form of the encryption key that we generated in the step a) d. When user share a file, we need also send back the encrypted key to their browser, then decrypt it with their password and add the decryption_key into the sharing-link in form: when another user download a file, we will use this decryption key to decrypt the file Thanks & regards,

...will poll a folder on an SFTP site at a set frequency, on a new file being identified the file will be moved from the SFTP site to a folder on a file server (UNC path). The above tasks may have multiple instances, so that files can be moved from different locations/SFTP sites if required. Ideally using free software such as Filezilla, putty etc Milestone 2: File transfer with encryption /decryption Similar to Milestone 1, but files need to be encrypted before sending to the SFTP using a PGP key. Files being received from the SFTP need to be decrypted after being moved to the Windows Server. Further details will be provided for this milestone to the successful freelancer. You will not be given access to the server or be given the SFTP details, so instructions will b...

CRACKING A CIPHER (30 points) Choose a substitution cipher and call it CIPHER. Write a C program that implements your CIPHER. Write a C program CRACKER that uses the letter frequency count method to decrypt the ciphertext generated by your CIPHER. CRACKER should take as input a ciphertext ctext generated by CIPHER and return a "decrypted" form of ctext. The decryption is not expected to be perfect! You may hard code your input plaintext or read it from a file. Your CIPHER and CRACKER should not remove blanks, capitalizations, and punctuation marks! You do not have to encrypt digits. A table containing the relative frequencies of English letters can be found at ~mec/2003-2004/cryptography/subs/frequencies.html. (10 points- Written) Answer the following questions:

...into blocks of size t. Recall that within each block, the Vigen`ere cipher works by encrypting the ith character with the ith key (using a basic cipher). Letting the key be k1, . . . , kt, this means the ith character in each block is encrypted by adding ki to it, modulo 26. The proposed modification is to encrypt the ith character in the jth block by adding ki + j modulo 26. (a) Show that decryption can be carried out. (b) Describe the effect of the above modification on Kasiski’s attack. (c) Devise an alternate attack that works better than Kasiski’s attack....
