Code must be only with System or Microsoft Libraries otherwise with other libraries ready to be linked to MS SQL (BouncyCastle library is isn't). Code must have two functions: EncryptRSA (string plainText, string|byte[] publicKey) returns Base64 encrypted plainText. DecryptRSA (string encryptedText, string|byte[] publicKey) returns plainText as string. Public Key may be in formats attached to this question. 1. PEM 2. Sun RSA public key, 2048 bits - info 3. DER

Hi ! I would like to work with a FullStack Developer on an urgent project. A Web Application should be implemented in Java (preferably) or any other language such as C++/ C# (not wordpress, joomla etc). For the security part you can use libraries e.g. for Java (shiro, owasp security framework, jguard, bouncycastle), for .Net (.NET Framework) etc. Together with the code, I will need 2-3 pages of explanation of work and another word file with screenshots of the app. Also a video of using it would be great. Analytical details will be given in a doc in chat. Also I will send you some code that may be useful. Deadline: 23/24 - 09 - 2022

I need to create a public / private key pair using EC curve:secp256r1. I am using the BouncyCastle crypto library. The attached code works fine to get the private key. But, I am not sure how to convert it to a string format. Should I convert to hex? Integer? I am also not sure if I need to use "serialized". I need both the public and private keys in a string format. Code is attached. I will pay up to $50 for the answer. Code snippet below. ------------------------------------------------------------------------------- try { ECKeyPairGenerator gen = new ECKeyPairGenerator(); SecureRandom secureRandom = new SecureRandom(); X9ECParameters secnamecurves = ("secp256r1"); ECDomainParameters ecParams = new ECDomainParameters(()

I am trying to implement an Encryption / Decryption system within my Android application. But so far its going no where. There is a lot of deprecated methodes and documentation to start with. I maybe say it simple but I want a secure and simple method to encrypt and decrypt text messages and files(Photos). I prefer BouncyCastle library if its possible. This is what I come up with. ECDSA SECG - SEC 2 or Brainpool For ECIES I want to use P-521 elliptic curve for the public-key calculations and PBKDF2 for KDF function and AES-GCM for symmetric cipher and HMAC-SHA512 for MAC algorithm. If you know a secure method please let me know.

...application here: but it needs to be Core 2.0 compliant (I don't know if the above linked solution is). Furthermore I need to encrypt arbitrarily long text so I don't know if AES will suffice. If interested in this project please respond with what kind of encryption method e.g. AES, TripleDES, etc. you think would be suitable for arbitrary length text encryption with good security vs. encryption speed. It will probably take me a few days to choose someone for the project and it will depend on mentioning an encryption algorithm (so that I know the project description has been read). Product should be a ASP Core C# form with buttons and textbox's for the key, encryption and decryption

...E3DES(p) = EDES(k1,DDES(k2,EDES(k1, p))) Here, p is the plaintext to encrypt, EDES is the usual DES encryption algorithm and DDES is the DES decryption algorithm. This strategy doubles the number of bits in the key, at the expense of performing three times as many calculations. This approach was shown to offer only the security of a 57-bit key rather than 112 bits as you might expect.) The TripleDES decryption algorithm is just the reverse: D3DES(c) = DDES(k1,EDES(k2,DDES(k1, c))) For this part of the project, implement a class called TripleSDES that provides the following methods and calculates the TripleSDES encryption. public static byte[] Encrypt( byte[] rawkey1, byte[] rawkey2, byte[] plaintext ) public static byte[] Decrypt( byte[] rawkey1, byte[] rawkey2, byte[] c...

Submit the screenshots and your source code when your program is complete. Hints: Do not attempt to implement AES on your own.

I need a small software written in Java and using BouncyCastle library (). The application can be in CLI or in a very simple GUI interface. It should have basically 2 functions: 1 - Sign a file: In this option the user should select a digital certificate in PKCS#12 format (using pfx or p12 extension) and any file in the system. After validate the certificate (explained below) the application will create a digital signature of the selected file and save it on a second file with the same name but with a p7s extension and using CMS/PKCS#7 format. 2 - Check a signature: The user will select the signed file, the p7s file related and the certificate. After validate the certificate (explained below), it should check if the signature is valid. Certificate

I have 2 functions (with around 5-10 sub functions all together) in java that need to be converted into javacard 3.0.1. The functions are fully working and tested, each function output is a hash. Functions i have in java are using DES and TripleDES algorithms (the pure implementation, not using crypto library of java or any additional library). However, if it helps - you can modify them to use javacardx crypto library, please note that there are some logical shifts inside the functions and int variables as well. You have to specify in your bid how are you going to convert them. Project budget is 150$. After completion during next 2 weeks freelancer will receive 400$ of bonus. Regards!

The Android operating system includes a customized version of Bouncy Castle and provides a limited set of cryptographic features. The SpongyCastle library, based upon BouncyCastle, can be used to provide additional functionality on Android. A project I developed uses SpongyCastle on Android, creating asymmetrical key pairs that are used for ECDH key exchange, allowing users of Android devices to send end-to-end encrypted messages to each other. We are using the curve secp256k1 on Android, and on iOS. iPhone devices do not allow us to use the same cryptographic libraries, so we need assistance from an experienced iOS developer who can develop code for the iPhone so that our iOS app can create ECDH key pairs using the curve secp256k1, and so that messages cre...
