I've successfully set up an OpenVPN server using OpenWrt on my Linksys 3200acm router, generating a profile that functions flawlessly on both my mobile device and Windows application. However, when attempting to use another OpenWrt router as a client, I've encountered connectivity issues. Based on my analysis, it appears to be a cipher-related problem. I'm currently seeking the expertise of a freelancer who can address this cipher issue on the client side. The goal is to establish a functional OpenWrt client VPN using the provided profile. If you have the skills to troubleshoot and resolve this matter, please reach out. Your assistance in ensuring a smooth connection between the routers would be greatly appreciated.

...binary data intended for encryption, outFile is the output file where you save all the necessary data for decryption, and publicKeyFile is the public 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 set...

At the point I circled in red, it is above 60 in 4 different time periods. I want it to scan the coins that meet these conditions and notify me. Or vice versa, when it is below -60 in 4 different time periods. It takes time to look at different times and find the coins above 60 or below -60. The only indicator is that I want it to notify me of the coins that meet these conditions.I want to set time zones
I want a scanning feature for this indicator. I want it to notify me if it is above or below a certain level, such as 30 min 1h 4h 1d for different time intervals at the same time. For example, I want it to scan and display the coins in binance. If there is something you do not understand, you can write again. tradingview

I want all references, inputs, and options for multi time frame (MTF) removed so it only uses the current chart timeframe. The indicator is Market Cipher B w/ Divergences by VuManChu. I have updated it to V5 and will upload the file.

When she gave you your secret key, Alice told you that she will use use AES-128-bit in cipher block chaining mode (CBC). Alice encodes strings as ‘utf-8’ and uses PKCS padding to allow messages whose size is not dividable by the block size. note: usually libraries handle the padding implicitly. Start your conversation with Alice, receiving her first encrypted message. Use the artificial TA to get convincing arguments to rely to Alice. You may need to exchange more than one message with her. You will know she is convinced when she sends you a unique “I’m convinced” message that has a token. Submit this token and your code to our grading system to pass this task.

Hi Harish Kumar,I noticed your profile and would like to offer you my project. The requirement for my project is to build a Cryptoprocessor using RISC -V Architecture on Vivaldo. We would be running a lightweight Cipher used in EV control unit (EV-ECU) . Aim is to carry out additional customization of instruction of Chiper, inject errors and collect data. Thereafter analyse the data obtained using AI-ML and be able to predict the type of error. The first stage is to Create the Cryptoprocessor on Vivaldo. I have found a research topic that guides on the same. . Need your guidance and help in this regard. We can discuss any details over chat.
