# Rsa 2048 and aes 128 ciphers

## Cracking weak rsa with python

Thank you to all who helped. I am a 78-year-old great-grandmother who is behind the times when it comes to computer technology and would appreciate any support. My issue has been resolved. One of my grandchildren suggested that I use the following phrase:

The biclique attack will recover the key for AES-128 with a computational complexity of 2126.1. The computational complexities of 2189.7 and 2254.4, respectively, refer to biclique attacks on AES-192 and AES-256. With complexities of 299.5 and 2176 in both time and data, related-key attacks can break AES-256 and AES-192. [2] The Advanced Encryption Standard (AES), also known as Rijndael (Dutch pronunciation: [rindael]), was developed by the United States National Institute of Standards and Technology (NIST) in 2001 as a specification for the encryption of electronic data. [4] AES is a subset of the Rijndael block cipher[3], which was created by Vincent Rijmen and Joan Daemen, two Belgian cryptographers who submitted a proposal[5] to NIST during the AES selection process. [6] Rijndael is a cipher family of various key and block sizes. NIST chose three Rijndael family members for AES, each with a block size of 128 bits but three different key lengths: 128, 192, and 256 bits.

Why do we use RSA encryption for ANY email, correspondence, or data encryption when everyone on the internet claims that AES-256 is much more secure than RSA-2048? If this is the case, why do encrypted email services like Protonmail use RSA encryption for email correspondence when AES-256 is more secure?
According to what I’ve read, brute force attacks are currently impossible to smash AES-256, but RSA isn’t as difficult to crack. As compared to a symmetric cipher like AES, why is this approach still used in cryptography?
Is it safer to use AES-256 or RSA-2048 to send protected and encrypted plaintext of – for example – two complete A4 pages of text? I know that using AES makes me much stronger and quicker, but maybe I’m missing something?
Now, the power of RSA is determined by the size of its modulus. You can generate an RSA keypair with a large enough modulus that, to the best of anyone’s knowledge, breaking the RSA key by factoring will take as much effort as breaking AES256 by brute force search. Unfortunately, as the modulus grows larger, RSA becomes very sluggish.

### How to get rid of (.locky extension) rsa-2048 and aes-128

A. It appears that a few keystrokes associated with my Acrobat software corrupted my computer with malicious malware, resulting in the conversion of approximately 15,000 files to an OSIRIS identification (unknown to me), such as 9795.98a.32: Please see the notation below, which I was able to open in one obscure PDF file and which provided me with instructions for next steps.
My files such as JPG, PNG, BMP, PDF, and TIFF are no longer openable due to the actions of this malware! My Photoshop files, such as PSD and RAW, seem to be unaffected. There’s also a lot of bad English in the quote, which points to a foreign agency.
B. QUESTION: Because this appears to be a ransom, has anyone heard of it? If so, how can I restore the file type identities to their original state without paying a fee and thereby deepening my involvement with a shady organization?
Have you made daily backups of your computer? If you’re using an optical drive, don’t leave it plugged in. I would recommend going to one of the free malware removal sites that we recommend if you have any hope of having this cleaned up. Please choose one and stick with it until they tell you that your machine is clean.
