Convert NSData to String?

Question

I am storing a openssl private Key EVP_PKEY as nsdata. For this I am serializing into a byte stream using the code below

unsigned char *buf, *p;
int len;
len

A simple way to convert arbitrary NSData to NSString is to base64 encode it.

NSString *base64EncodedKey = [keydata base64EncodedStringWithOptions: NSDataBase64Encoding64CharacterLineLength];

You can then store it into your database for reuse later. Just decode it back to NSData.
