+ * base64 - base64 encoding and decoding (rfc4648).
+ *
+ * base64 encoding is used to encode data in a 7-bit clean manner.
+ * Commonly used for escaping data before encapsulation or transfer
+ *
+ * Example:
+ * #include <stdio.h>
+ * #include <string.h>
+ * #include <ccan/base64/base64.h>
+ *
+ * int main(int argc, char *argv[])
+ * {
+ * char *base64_encoded_string;
+ * int i;
+ *
+ * // print the base64-encoded form of the program arguments
+ * for(i=1;i<argc;i++) {
+ * size_t unencoded_length = strlen(argv[i]);
+ * size_t encoded_length = base64_encoded_length(unencoded_length);
+ * base64_encoded_string = malloc(encoded_length);
+ * base64_encode(base64_encoded_string, encoded_length,
+ * argv[i], unencoded_length);
+ * printf("%s\n", base64_encoded_string);
+ * free(base64_encoded_string);
+ * }
+ *
+ * return 0;
+ * }
