boolToPtr returns the pointer to a boolean.

CalculateBCHash returns the Bitcoin hash (double sha256) of the given transaction.

CleanEnvVar replaces all occurrences of illegal characters in an environment variable with the specified byte.

ComputeBitcoinAddress compute address from public key Key hash = RIPEMD-160(SHA-256(public key)) Checksum = SHA-256(SHA-256(Key hash)) first 4 bytes Bitcoin Address = Base58Encode(Key hash + Checksum).

ComputeCryptoHash should be used in openchain code so that we can change the actual algo used for crypto-hash at one place.

CopyFile copies a file from src to dst.

GenerateIDWithAlg generates an ID using a custom algorithm.

GenerateIntUUID returns a UUID based on RFC 4122 returning a big.Int.

GenerateShortID generates a short id (length = 9).

GenerateUUID returns a UUID based on RFC 4122.

GenerateUUIDfromTxSHAHash generates SHA256 hash using Tx payload, and uses its first 128 bits as a UUID.

StringToPtr returns the pointer to a string.

TimeToPtr returns the pointer to a time stamp.

UintToPtr returns the pointer to an uint.

validate base64 encoding string.

validate txid from blockchain return.

validate UUID base on RFC 4122(uuid v4).
