C++ (Cpp) base16_encode_update Examples

Example #1

File: default_encoders.cpp Project: Reisen/Keyspace

string
hex_encode(uint8_t *data, size_t data_len) {
    uint8_t *ascii_hash = new uint8_t[data_len * 2];
    base16_encode_update(
        ascii_hash,
        data_len,
        data
    );

    string hexed{(const char *)ascii_hash, data_len * 2};
    delete [] ascii_hash;

    return hexed;
}
