expand_more MySQL's FROM_BASE64(~) method decodes a base64 encoded string and returns the resulting binary string.
NOTE
base64 is a method to encode binary data using ASCII characters. As ASCII characters are available in most character sets, this means there is a low chance of data corruption. Each base64 digit represents 6 bits of data. Therefore, 3 bytes (24 bits) can be represented using 4 base64 digits.
There are a few rules followed by FROM_BASE64(~):
Encoding for alphabet value 62 is
'+'Encoding for alphabet value 63 is
'/'Newlines, carriage returns, tabs and spaces are ignored when decoding.

SELECT FROM_BASE64(NULL);
+-------------------+| FROM_BASE64(NULL) |+-------------------+| NULL |+-------------------+
