In which implementation do you think I found this?

typedef struct {
          /* Status information */
          int isPublicKey;                        /* Whether this is a 
public or private key */

          /* Public components */
          unsigned char n[ CRYPT_MAX_PKCSIZE ];   /* Modulus */
          int nLen;                                       /* Length of 
modulus in bits */
          unsigned char e[ CRYPT_MAX_PKCSIZE ];   /* Public exponent */
          int eLen;
...
}
