Crc32ChecksumBytes calculates a CRC32 checksum of the given string, returning the bytes of the checksum.

DecodeBase62 decodes a base62 encoded string, returning a byte slice of the given length; if the given length is < 1, the length of the returned byte is not guaranteed; if the given length is >= 1, the length of the returned byte slice will be of the given length; if the data cannot fit in a byte of the given length, a zeroed byte slice of the given length and false will be returned; if a decoding error is encountered, a nil byte slice and false will be returned; for toggling letter case of input string if producer's alphabet is different than Golang's big.Int alphabet; this is the dumb way of switching between 0-9,a-z,A-Z and 0-9,A-Z,a-z alphabets.

EncodeBase62 encodes bytes into a base62 encoded string, returning the encoded string; allows for toggling letter case of output string if consumer's alphabet is different than Golang's big.Int alphabet; this is the dumb way of switching between 0-9,a-z,A-Z and 0-9,A-Z,a-z alphabets.

GenerateCrc32Uint32 calculates a CRC32 checksum of the given string, returning the checksum as uint32.

GenerateSecureRandomBytes returns a byte slice of the given length w/ cryptographically secure random data; if an error is encountered while attempting to generate secure random data (resulting in a partially filled buffter), then the rest of the buffer is filled with insecurely generated random data.

SelectInsecureRandomInt selects a random value from the given arguments using insecure randomness.

SelectInsecureRandomStr selects a random value from the given arguments using insecure randomness.
