using the GC. The versions returning static arrays use pass-by-value for the return value, effectively avoiding dynamic allocation.
toHexString
fn
char[num * 2] toHexString(Order order = Order.increasing, size_t num, LetterCase letterCase = LetterCase.upper)(const ubyte[num] digest)Used to convert a hash value (a static or dynamic array of ubytes) to a string. Can be used with the OOP and with the template API.
The additional order parameter can be used to specify the order of the input data. By default the data is processed in increasing order, starting at index 0. To process it in the opposite order, pass Order.decreasing as a parameter.
The additional letterCase parameter can be used to specify the case of the output data. By default the output is in upper case. To change it to the lower case pass LetterCase.lower as a parameter.
Note
The function overloads returning a string allocate their return values
