Is there a FCL library that can be used to convert a large integer into base64 format?

Define  "large  integer"  ... in case you mean a normal integer/int64:
IntToHex(...);

Do you know about the base64 unit?

I mean int64 into base64 encoding, as in the mime type.

Oops, my bad. Then yeah, as Henry said the base64 unit should help. Depending on who and how the number is to be decoded then, you could also take a which can convert from decimal
into any given number system. (... and the opposite Numb2Dec)

I have it working now, but I have noticed that if the length of string is not a multiple of 3, it crashes.

Is there a way of adapting a string with a length that is not a multiple of 3 to allow it to encode, but yet
decode it back to the original string?

The other part is I want to pass the int64 in binary form.

Will a pointer to the integer and setting the length to copy to 8 be the right approach?

i.e

Encoder.CopyFrom(P^.Integer64Value, 8)

Of course the 8 will generate an error.
