My current project involves Mallox Ransomware decryption and I'm in need of experienced help. This project requires intense security knowledge and the use of advanced encryption methods - AES, Triple DES, and RSA. I believe the project to be of a hard difficulty level and am not specifying a language preference. If you think you're up for the challenge and want to join the fight against cybercrime, I'd love for you to help me out on this project.

...key that will be used to encrypt the symmetric key. The parameter symmetricCipher is the name of the symmetric cipher. The function generates a symmetric (shared) key and an initialization vector (IV), which will be the input to the symmetric cipher symmetricCipher. You will encrypt the data in inFile with this cipher, key, and IV. Also, you encrypt the symmetric key with an asymmetric cipher (RSA) using the public key stored in publicKeyFile. OpenSSL does most of the work for you: PEM_read_PUBKEY reads the public key, EVP_SealInit generates a shared key and IV (if necessary), encrypts the shared key, and sets the context, EVP_SealUpdate and EVP_SealFinal work the same as in previous tasks. Hybrid encryption is able to encrypt for multiple recipients. The data is encrypted onl...

I am the ssh client and recently upgraded to Ubuntu 22.04 which runs openSSH 8.9 However one of the servers I am trying to reach is running an older version of openSSH. The admin on the server side can't upgrade his version of openSSH. Because on my new version of openSSH, the ssh-rsa (the most used key type) is disabled, I am no longer able to sftp into the server using my existing key pair. I am trying to use the "-oHostKeyAlgorithms=+ssh-rsa" flag on my command line, which is supposed to allow me to continue to use my old key; however, while this gets me further along, it is ultimately unsuccessful.

Hi, I have an integration that I am working on that requires a PHP file to collect some/all/daily data from an SFTP remote folder. The host has the public key and we have the private key (in text form - might need a change of format?) (RSA SSH-2 2048 bit compliant). The PHP file will run from our server, log into the SFTP folder using the supplied credentials and download the necessary file to our server. Please bid your total price, not hourly. If you bid a low amount, and increase the price before work, you will be blocked.

...this assignment, the task is to implement a simulation of TLS in any coding language of your choice, including the two key exchange methods (RSA and Diffie-Hellman). The implementation is only a simulation of what happens in real-life. You can use variables, classes, methods to represent the operations done by the client and the server. No actual deployment of websites is necessary. The TLS handshake required to be implemented will proceed as follows. The client generates a nonce of size 32 bytes. You may use an existing random number generator or library for this step. The client sends the nonce to the server along with a flag that is set to 1 if RSA will be used for key exchange, and set to zero if Diffie-Hellman will be used. You may randomly set this flag. The server r...

Hi, I need a cryptography programmer who can code for me an RSA cryptography system that can encode and decode files using a public and private key. I already have the working SHA-256 hash project but I need someone to help me with the RSA code using the NaCl library. I am not a cryptology expert by any means but from what I understand, the idea would be that we would hash the data and then sign the hash. This will prove that whoever generated this hash has the private key. Then you get the data that you want to verify, calculate the hash on it and then check that. If the calculated hash matches the one in the signature then the signature is valid. At this point we will have have high confidence that the data has not been changed and that it was generated by someone that h...

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.

This goes to anyone who has knowledge in secure software and has experience dealing with RSA public and private keys. You will need to customize the supplied json order file to provide information and then encrypt that json order using aes encryption with the supplied ke and IV then base64 encode the result. However, you may need to convert the message to a byte array from strings to work with the encryption algorithm and generate a message digest using SHA512. I will provide additional files and further instructions upon contacting me. Please also provide your budget first as I am on a strict budget, thank you.
