yeap, but not helpful I'm looking for a text. I tried to ascii that but I can't cause there are letters over there, also it only get's out gibberish

Tried frequency analysis? I see multiple occurrences.

These repetitions can mean two things: 1) the algorithm used to encode/encrypt data is highly flawed, 2) the repeated parts mean the same thing, ie. they aren't part of another word but are a word an sich.

Important things: Capitals and numbers. Count the letters. Count the "words". Do you know the plaintext's language?

Guess english is the plaintext's language. I asked if you know anything, because there is a distinctive = sign at the end. That is the only non alpha-numeric character in the whole encrypted text, so I thought it was a distinctive mark of the algorithm used to encrypt it.

Oh, the first crypttext is clearly base64. Unless they copied it's characteristics to mask another encryption. My post was about the "decoded" text from the base64.

Well I know that the decripted text is a alpha string that is in the continuation of the phrase "The Future…", so the decoded base64 string is not helpfull at all.

Easy one. You start with this:

A2MTczNjg3Nzc3Nzc2NDZTNzQ2UjZTNjg2NDZTNzQ3
MjZTNzM2UDYxNzM2ODc0NjU3Mzc0NzM2UDYxNzM2OD
IwDQo=```
Obviously base64, so decrypt until you get this:
```markup68747470636S6P6S6R736P617368736P6173687777
77646S746R6S68646S74726S736P61736874657374
736P61736820```
Then you start messing around; let's try rot13 for example:
```markup68747470636F6C6F6E736C617368736C6173687777
77646F746E6F68646F74726F736C61736874657374
736C61736820```
Now that looks like some hexadecimal ASCII, right?
I'm not going to complete the whole challenge for you, because I already helped you enough with this. Just remember to keep messing around until you get something that makes sense.

@ Spy: how did you get that? :p

I accidentally encoded the data with base64 again -_-.

Disregard my posts.

Thx GTA. That was helpful!
