Decoding happens in much the same way. I report the number of bytes. The ‘data’ member is just a byte string of a gzipped file. Base64 is a group of "binary to text" encoding schemes. here is the code that GZIP's it then encrypts it and then base 64. If you intercept a SAML Message, you will turn it in plain-text through base64 decoding. Java gzip compress/decompress string. The constants defined in Base64 can be OR-ed together to combine options, so you might make a call like this: String encoded = Base64.encodeBytes ( mybytes, Base64.GZIP | Base64.DO_BREAK_LINES ); to compress the data before encoding it and then making the output have newline characters. gzip without header and base 64 encode, in Node. Basically, Base64 is a collection of related encoding designs which represent the binary information in ASCII format by converting it into a base64 representation.

Gzip worked well on the text file but slightly increased the size of the random data (which is guaranteed to happen in average on random data). Now, let's try base64 encoding first and then apply gzip: So, on random, uncompressible bytes, gzip mitigates the effect of base64 encoding, so that only 0.9% overhead are left.
