I need someone who can still remove the encryption so that I can open, read, and edit the files normally. You will receive the encrypted PDFs immediately after project start. Your task is to return fully decrypted copies that preserve the original layout, images, and metadata. If your workflow relies on tools such as OpenSSL, QPDF, or any other specialized forensic utilities, just let me know—whatever gets the job done cleanly. A short outline of your approach (no trade secrets, just enough to confirm feasibility) will help me award the project quickly. This an example, if you can decrypte it i'll send ...

I have a small, password-protected text file that was encrypted with OpenSSL using AES-256. The password is definitely correct, yet the usual OpenSSL command line fails to decrypt—either producing garbled output or throwing a “bad decrypt” error. My goal is straightforward: identify why the routine is failing and supply a reliable method (script, one-liner, or documented steps) that successfully returns the original clear-text. You may need to inspect the file header, check salt or IV handling, verify padding, or recreate the encryption parameters before running a working OpenSSL, OpenSSL-compatible Python, or similar solution. Please let me know what tools or commands you plan to test so I can match them in my environment. Important ethical ...

The current error is “stream_socket_enable_crypto(): OpenSSL:0A000438:SSL routines::tlsv1”, so Mailwizz times out the moment it tries to negotiate TLS. What I need from you • Make sure each domain routes mail through its assigned IP and authenticates cleanly. • Open and verify port 587 on every address, confirm STARTTLS works, and eliminate the OpenSSL/TLSv1 complaint. • Leave the existing Virtualmin/Apache stack intact; this is purely a mail and networking fix. • Hand me a brief rundown of what you changed so I can repeat it if I...

Hi. I need the following AES -256-CBC encryption, decryption modules. 1. (For Windows) Encryption, decryption modules running in C++ (MSVC 2017) - Using bcrypt Library (please dont use OpenSSL) 2. (For macOS, Linux) Encryption, decryption modules running in Qt 6.x 3. Encryption, decryption modules running in PHP 8.x - Using openssl_decrypt * The content (Only text) to be encrypted includes 2-byte codes such as Japanese, Chinese, and Korean. * Also, the encryption and decryption results should be returned in base64 format. * The ultimate goal is to encrypt in modules in C++ and Qt, and receive them in PHP and decrypt them.
