Its not always necessary to have the highest level of encryption for every piece of data.

You never know -- some protocols may interpret your binary data as control characters (like a modem), or your binary data could be screwed up because the underlying protocol might think that youve entered a special character combination (like how FTP translates line endings).

This is why there are multiple forms of Base-64 ( en.wikipedia.orgwikiBase-64 ).

In theory, you could represent a single number this way using these 64 characters as a base-64 number instead of the 10 characters we normally use to represent base-10 number.

It takes 4 characters per 3 bytes of data, plus potentially a bit of padding at the end.

The standard alphabet uses A-Z, a-z, 0-9 and and, with as a padding character.

Binary data should be treated as binary data, and not treated as text.

Ive seen literally hundreds - possibly thousands - of questions on SO which basically boil down to people not taking enough care over this distinction.

Its a convenient way to storetransmit binary data over media that is specifically used for textual data.

Therefore the bloating is only a mere 43 1.3333333 times the original.

Converting the resulting bytes into Base64 makes it much easier to display the hash especially when you are comparing a checksum for integrity.

Hashes are so often seen in Base64 that many people mistake Base64 itself as a hash.

Anyone can convert the Base64 string back to its original bytes, so it should not be used as a means for protecting data, only as a format to display or store raw bytes more easily.

Even in a database, and especially in a file (if fixed-length records are used, or the bytes are the only content).

Base64 is typically used when those bytes are intended to be transmitted somewhere, particularly over a channel that might lop off bits or interpret some of the bytes as control codes.

I agree if you can store it as raw bytes then by all means, but base64 is for those situations when you cannot.

These are simply two common scenarios where you will see it.

Hex digits can represent any binary data, but base 64 has the advantage of taking up a lot less space since it uses more characters.

When these attachments are sent over internet (which is basically in the form of binary data), the probability of binary data getting corrupt is high in its raw form.

So to make string length multiple of 3, we must add 2 bit padding to make length 6.

In this method, every byte transmitted would have 7-bits of data, and the 8th would be 1 or 0, to force the total number of 1 bits in the byte to be even.

Just imagine a situation where control characters are used to trigger special actions andor that only supports a limited bit width per character.

Base64 transforms any input into an encoding that only uses alphanumeric characters,, and the as a padding character.

So what I did to support full 4-byte unicode over MySQLs utf8 Well, base64 encode strings when storing into the database and base64 decode when retrieving.

Second degree sensitive data is okay to be base64 encoded to make it unreadable by db administrators.
