The above given text is encoded with a some kind of substitution algorithm. Also we can observe that some part are repeating themself.

First example:

Second example:

Third example:

After replacing the above strings with spaces (“ “), you obtain the following:

By searching for “{“ or “}” we can obtain the exact block of the flag. Also note that numbers or spaces are not substituted.

From that flag format we know that “wsxcfe” is the letter “D” and if we take a look at our keyboard, we get the following information:

By mapping all blocks to our keyboard we can obtain all letters in this encoding. Therefore there is an almost perfect decryption tool:
