michael@0 22 * Explanation for the definition of MAX_WRAPPED_KEY_LEN:
michael@0 23 *
michael@0 24 * It's used for internal buffers to transport a wrapped private key.
michael@0 25 * The value is in BYTES.
michael@0 26 * We want to define a reasonable upper bound for this value.
michael@0 27 * Ideally this could be calculated, but in order to simplify the code
michael@0 28 * we want to estimate the maximum requires size.
michael@0 29 * See also bug 655850 for the full explanation.
michael@0 30 *
michael@0 31 * We know the largest wrapped keys are RSA keys.
michael@0 32 * We'll estimate the maximum size needed for wrapped RSA keys,
michael@0 33 * and assume it's sufficient for wrapped keys of any type we support.
michael@0 34 *
michael@0 35 * The maximum size of RSA keys in bits is defined elsewhere as
michael@0 36 * RSA_MAX_MODULUS_BITS
michael@0 37 *
michael@0 38 * The idea is to define MAX_WRAPPED_KEY_LEN based on the above.
michael@0 39 *
michael@0 40 * A wrapped RSA key requires about
michael@0 41 * ( ( RSA_MAX_MODULUS_BITS / 8 ) * 5.5) + 65
michael@0 42 * bytes.
michael@0 43 *
michael@0 44 * Therefore, a safe upper bound is:
michael@0 45 * ( ( RSA_MAX_MODULUS_BITS / 8 ) *8 ) = RSA_MAX_MODULUS_BITS
