Hi Bialecki,
for base64 encoding/decoding you can use openSSL Library which providing by
MAC OS.
I can give you code snippets for encoding and decoding string.
#include <openssl/bio.h>
#include <openssl/evp.h>
- (NSString *)base64EncodedString
{
// Construct an OpenSSL context
BIO *context = BIO_new(BIO_s_mem());
// Tell the context to encode base64
BIO *command = BIO_new(BIO_f_base64());
context = BIO_push(command, context);
// Encode all the data
BIO_write(context, [self bytes], [self length]);
BIO_flush(context);
// Get the data out of the context
char *outputBuffer;
long outputLength = BIO_get_mem_data(context, &outputBuffer);
NSString *encodedString = [NSString
stringWithCString:outputBuffer
length:outputLength];
BIO_free_all(context);
return encodedString;
}
+ (NSData *)dataByDase64DecodingString:(NSString *)decode
{
decode = [decode stringByAppendingString:@"\n"];
NSData *data = [decode dataUsingEncoding:NSASCIIStringEncoding];
// Construct an OpenSSL context
BIO *command = BIO_new(BIO_f_base64());
BIO *context = BIO_new_mem_buf((void *)[data bytes], [data length]);
// Tell the context to encode base64
context = BIO_push(command, context);
// Encode all the data
NSMutableData *outputData = [NSMutableData data];
#define BUFFSIZE 256
int len;
char inbuf[BUFFSIZE];
while ((len = BIO_read(context, inbuf, BUFFSIZE)) > 0)
{
[outputData appendBytes:inbuf length:len];
}
BIO_free_all(context);
[data self]; // extend GC lifetime of data to here
return outputData;
}
