Online Base64 Encoder

how to convert byte data to a string so I perform base64 decode on it and then zlib decompress it.

example: data = b'eJzLSM3JyQcABiwCFQ=='

Zlib::Inflate.inflate(Base64.decode64(bin_to_hex(data)))def bin_to_hex(s)s.unpack('C*').firstend

I'm getting "\xE2" from ASCII-8BIT to UTF-8 also getting undefined methodunpack'`

Is it possible for a string generated from a base64 encoding to have a space (' ') in it?

one of my project i need decode the following string (it changes time to time but format is same).

at first glance it seems it is base64 encoded, so i have tried to decode using base64 but it returns garbage.

can any on help please?

I tried to solve this problem but I never come to a solution that would work for me. The problem is that I am getting warings about BASE64Encoder. Is there any other way to do this without the BASE64Encoder?

The code:

public static String Encrypt(String Data) throws Exception {    Key key = generateKey();    Cipher c = Cipher.getInstance(ALGO);    c.init(Cipher.ENCRYPT_MODE, key);    byte[] encVal = c.doFinal(Data.getBytes());    String encryptedValue = new BASE64Encoder().encode(encVal); //Here is the problem    return encryptedValue;}public static String Decrypt(String encryptedData) throws Exception {    Key key = generateKey();    Cipher c = Cipher.getInstance(ALGO);    c.init(Cipher.DECRYPT_MODE, key);    byte[] decordedValue = new BASE64Decoder().decodeBuffer(encryptedData); //Another problem    byte[] decValue = c.doFinal(decordedValue);    String decryptedValue = new String(decValue);    return decryptedValue;}private static Key generateKey() throws Exception {    Key key = new SecretKeySpec(keyValue, ALGO);    return key;}

I've been reading about base64 conversion, and what I understand is that the encoded version of the original data will be 133% of the original size.

Then, I'm reading about how YouTube is able to have unique identifiers to their videos like FJZQSHn7fc and the reason was: an 11 character base64 string can map to a huge number.

Wait, say a huge number contains 20 characters, then wouldn't a base64 encoded string be 133% of that size, not shorter?

I'm very confused. Are there different types of base64 conversion (string to base64 vs. decimal to base64), once resulting in a bigger, and the other in a smaller resulting string?
