hello world welcome back to another imaginary CTF 2024 writeup video in this video weamp;#39;ll be walking through the crypto challenge base 64 letamp;#39;s get into it yet another B 64 decoding challenge okay so I have the files that give you downloaded over here letamp;#39;s go ahead and open this in code okay you have a main.py source code and an out.txt file with the secret key scanning through this main.py script we see that we have a Q being assigned the value 64 and then itamp;#39;s opening the flag file and then converting the flag to a long integer then itamp;#39;s initializing the secret key list and then itamp;#39;s looping through our flag integer and then itamp;#39;s appending to the secret key the flag integer mod Q so the remainder of the flag integer divided by q and then it floor divides the flag integer by q and then it assigns the flag integer to the quotient of that operation so itamp;#39;s clear that we need to reverse this so what Iamp;#39;m going

What is the padding in Base64?

Since the last bits cannot form a whole 6-bit string, the Base64 encoding adds padding to these strings until they docHub the appropriate length. And for representation purposes, each 00 padding is represented by an = sign, to instruct the decoder how many bits should be discarded from the end of the string.

What is a padding character?

A pad character is a special character used to fill or extend a data string. This practice is known as padding. Its often necessary because certain operations require data to be of a fixed length.

What character pads the end of Base64 encoded strings?

Base64 strings tend to end in one or two equal signs, but not always! These strings are not exact representations of the binary data in ASCII, because padding is applied to ensure the string length is a multiple of 4 characters. Each equal sign represents two bits of zero-padding.

What is the padding character in Base64?

The = sign is used to indicate padding if the input string length is not a multiple of 3 bytes. If we have four bytes for the input, then the base64 encoding ends with two equal signs, just to indicate that it had to add two characters of padding.

What is the radix 64 encoding?

What is Radix 64 Encoding? Radix 64 encoding allows binary data stored in octets (i.e. bytes) to be expressed as printable characters.

What is the valid padding in Base64?

Base64 always encodes data in buckets of four symbols. For every three input bytes (24 bits), four 6-bit characters from the base64 alphabet are used (which also equal 24 bits). If the input data contains less than three bytes, then the missing bits are compensated with the padding character =.
