 * various errors and violations.  This is not a part of the library
 * itself, because the allowed violations are chosen arbitrarily and
 * do not follow or establish any standard.
 *
 * It also contains code to serialize private keys in a compatible
 * manner.
 *
 * These functions are meant for compatibility with applications
 * that require BER encoded keys. When working with secp256k1-specific
 * code, the simple 32-byte private keys normally used by the
 * library are sufficient.
