Can I and How Decrypt this Online

Although I had a security course in school a long time ago, I am effectively new to cryptography.

I have an encrypted text, the encryption key of 44 characters, the encryption method, (Fernet, which uses AES), the mode (CBC), the length of the key (128-bit), the padding (PKCS7) and the authentication (SHA256).  The online decrypters I find do not provide the ability to enter all of these elements on one page.  Is it possible to decrypt it online?  Is there an order of steps that I have to use?

Thanks.

From whom did you receive the encrypted text? Contact them, as they'll likely

be the only party to tell you that. That's pretty much how the process works.

Can somebody help which decryption tool I need to use to decrypt this message?

I tried using base64 to text but no luck. Somebody send me the message and I cannot understand what is this.

Again, why don't you just ask the person who sent you the message?

They'll know what encryption they used. And if you refuse to, then

I have to consider the possibility that you're trying to decrypt a message

that wasn't meant for you.

 

Besides, even if I wanted to, I couldn't tell you how to decrypt something

based on a portion of it. That's the whole point of encryption, it prevents

people who weren't intended to get the message and read it from...

getting the message and reading it.

Actually the person who sent me the message is not in good terms with me. We were debating then he started to reply me with codes. The last code I cracked it and reply to him. Then he sent me this.

Get the key from him. There is literally no other

option. That's just how encryption works.

That's the thing. He does not want me to understand what he said. Otherwise he wouldn't deliberately encrypt it and send it to me. The first encrypted message was cracked by me. So I reply to him accordingly. Then he uses a different encryption to reply to me and I couldn't crack it.

Your "cracked" his first message? Then why can't you

"crack" the second?

 

Anyways, why would someone send you a message

that they didn't want you to be able to decrypt and read?

Why would they bother?

 

Sorry, but your story is not consistent with basic theory

about encryption. For that reason, I have to wonder

whether your intentions are what you claim or something

entirely different.

 

Read my previous post. As I said. This person is not in good terms with me. We were debating in normal language. Then suddenly he replied me with his first encrypted msg. I tried to search what the code means thru online and found out he was using ASCII code. So I decrypted using online tools. Once I know what he wrote (which was mocking me) then I replied to him using the same encryption. Then he replied to me using the code I shared. But I couldn't find what it is thru internet. Seems like base64 according to internet but when I use the tools the result was not readable.

So if you UNDERSTAND how the story goes, he deliberately tried to say something to me that I do not understand. It could be mocking, swearing or other message that was encrypted. In the end he does not want me to understand what he wrote. Kind of a coward right. So I wanted to know what he writes to me. That's all.

But thanks anyway for replying to me.

If you have assorted other data other than just the encrypted message and key, one of the above websites might be helpful...

You can search google and try to find out the website which member said but you have to basic knowledge about encryption.

The base64 text that you've pasted only decodes to encrypted binary, that's how these things work. Base64 (or Base32 or Ascii85 or UUencode or whatever) simply make encrypted anything readable, meaning sendable. Even if you know the cipher and password, you're still probably out of luck unless you also know the method of salting and number of (hashing) iterations, which can be tens or even hundreds of thousands of times.
