More information is needed to determine specifically what infection you are dealing with since there are many variants of crypto malware (file encrypting ransomware). RSA-4096 / RSA-2048 / RSA-1024 / AES-256 / AES-128 are encryption algorithms and not an explicit way of identifying a particular ransomware infection.
Are there any obvious file extensions appended to or with your encrypted data files (i.e. several random hexadecimal characters, words or email addresses)? If so, is the extension the same for each encrypted file or is it different?

Did you find any ransom notes and if so, what is it's actual name? These infections are created to alert victims that their data has been encrypted and demand a ransom payment. Check your documents folder for an image the malware typically uses for the background note. Check the C:\ProgramData (or C:\Documents and Settings\All Users\Application Data) for a randomly named .html, .txt, .png, .bmp, .url file. Most ransomware will also drop a ransom note in every directory/affected folder where data has been encrypted.

Did the cyber-criminals provide an email address to send payment to?

The best way to identify the different ransomwares is the ransom note (including it's name), samples of the encrypted files, the malware file itself, any obvious extensions appended to the encrypted files, samples of the encrypted files and information related to any email addresses used by the cyber-criminals to request payment.

You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections. If ID Ransomware cannot identify the infection, you can post the case SHA1 it gives you in your next reply for Demonslay335 to manually inspect the files.

Samples of any encrypted files, ransom notes or suspicious executable's (installer, malicious files, attachments) that you suspect were involved in causing the infection can be submitted here (https://www.bleepingcomputer.com/submit-malware.php?channel=168) with a link to this topic. There is a "Link to topic where this file was requested" box under the Browse... button. Doing that will be helpful with analyzing and investigating by our crypto malware experts.
