15 * various errors and violations. This is not a part of the library
16 * itself, because the allowed violations are chosen arbitrarily and
17 * do not follow or establish any standard.
18 *
19 * It also contains code to serialize private keys in a compatible
20 * manner.
21 *
22 * These functions are meant for compatibility with applications
23 * that require BER encoded keys. When working with secp256k1-specific
24 * code, the simple 32-byte private keys normally used by the
25 * library are sufficient.
