DecodeBase58Check
bool DecodeBase58Check(const std::string &str, std::vector< unsigned char > &vchRet, int max_ret_len)
Decode a base58-encoded string (str) that includes a checksum into a byte vector (vchRet), return true if decoding is successful.

DecodeBase58
bool DecodeBase58(const std::string &str, std::vector< unsigned char > &vchRet, int max_ret_len)
Decode a base58-encoded string (str) into a byte vector (vchRet).
Definition: base58.cpp:129

EncodeBase58Check
std::string EncodeBase58Check(std::span< const unsigned char > input)
Encode a byte span into a base58-encoded string, including checksum.

EncodeBase58
std::string EncodeBase58(std::span< const unsigned char > input)
Why base-58 instead of standard base-64 encoding?
