In my app I need to encode a string via base64, escape it's possible special characters and put it into a URL.
I do the following:
string = "[email protected]"
enc = OpenSSL::Cipher::Cipher.new('DES-EDE3-CBC')
enc.encrypt('dummy_salt')
encoded = URI.escape(Base64.encode64(enc.update(string) << enc.final))
The problem is, that ...
I need to send a public key created by RSA by SMS to another phone.
I am converting the 148 byte public key to base64 to be sent by SMS. But it increases the 148 bytes to 200 bytes when converted.
As byte[] cannot be directly sent by SMS, what are the other possible methods of converting them successfully to strings or equivalent which ...

Hi!
I have to send a file to my webservice, but the webservice assumes the file (byte Array) as a base64Binary.
Before the encoding, the byteArrayFile is saved on disk as a regular File. (I'm doing it just for testing)
So, in my Java client for webservice, I'm sending the information this way:
String file = new sun.misc.BASE64Encoder...
Hey guys,
I'm not much of a PHP expert. I'm encoding a URL with base64_encode.
I get quite a long encoded string with a lot of weird characters exactly as I want it to be.
Is there a way to trim this long line of characters to let's say 10 or 15 chars, so I can decode it later again?
I know there is trim() but that does not exactly wha...

Hi, I am now using python base64 module to decode a base64 coded XML file, what I did was to find each of the data (there are thousands of them as for exmaple in "ABC....", the "ABC..." was the base64 encoded data) and add it to a string, lets say s, then I use base64.b64decode(s) to get the result, I am not sure of the result of the dec...
Suppose you have a MD5 hash encoded in base64. Then each
character needs only 6 bits to store each character in the
resultant 22-byte string (excluding the ending '=='). Thus, each
base64 md5 hash can shrink down to 6*22 = 132 bits, which
requires 25% less memory space compared to the original 8*22=176
bits string.
Is there any Python...
Is it possible to do simple string concatenation to 'join' 2 base 64 encoded images together if the images have the same characteristics (width/height/color depth etc)?
eg
img1 w=100, h=200
img2 w=100, h=200
img1+img2 results in
img3 w=100, h=400
intuitively this feels like a stupid question since presumably the encoding includes...
Hi,
I have a very strange character encoding error:
I am sending a textfield to a script via jQuerys ajax function.
Assuming I want to send the euro sign
echo $string;
produces

however
echo base64_decode(base64_encode($string));
produces

any hints on how I could debug this problem?
