int | ec_seckey_import_der (const secp256k1_context *ctx, unsigned char *out32, const unsigned char *seckey, size_t seckeylen) |
These functions are taken from the libsecp256k1 distribution and are very ugly. More... | |
int | ec_seckey_export_der (const secp256k1_context *ctx, unsigned char *seckey, size_t *seckeylen, const unsigned char *key32, bool compressed) |
This serializes to a DER encoding of the ECPrivateKey type from section C.4 of SEC 1 https://www.secg.org/sec1-v2.pdf. More... | |

This serializes to a DER encoding of the ECPrivateKey type from section C.4 of SEC 1 https://www.secg.org/sec1-v2.pdf.
The optional parameters and publicKey fields are included.
seckey must point to an output buffer of length at least CKey::SIZE bytes. seckeylen must initially be set to the size of the seckey buffer. Upon return it will be set to the number of bytes used in the buffer. key32 must point to a 32-byte raw private key.

This parses a format loosely based on a DER encoding of the ECPrivateKey type from section C.4 of SEC 1 https://www.secg.org/sec1-v2.pdf, with the following caveats:
out32 must point to an output buffer of length at least 32 bytes.
