/*
* Explanation for the definition of MAX_WRAPPED_KEY_LEN:
*
* It's used for internal buffers to transport a wrapped private key.
* The value is in BYTES.
* We want to define a reasonable upper bound for this value.
* Ideally this could be calculated, but in order to simplify the code
* we want to estimate the maximum requires size.
* See also bug 655850 for the full explanation.
*
* We know the largest wrapped keys are RSA keys.
* We'll estimate the maximum size needed for wrapped RSA keys,
* and assume it's sufficient for wrapped keys of any type we support.
*
* The maximum size of RSA keys in bits is defined elsewhere as
* RSA_MAX_MODULUS_BITS
*
* The idea is to define MAX_WRAPPED_KEY_LEN based on the above.
*
* A wrapped RSA key requires about
* ( ( RSA_MAX_MODULUS_BITS / 8 ) * 5.5) + 65
* bytes.
*
* Therefore, a safe upper bound is:
* ( ( RSA_MAX_MODULUS_BITS / 8 ) *8 ) = RSA_MAX_MODULUS_BITS
*
