BeFoR64Base64 for Fortran

Pure Fortran 2003+ library for base64 encoding and decoding of intrinsic types

🔢

All intrinsic types

Encode and decode real, integer, and character variables — both scalar and array — of any kind. Unlimited polymorphic variables supported too.

📄

Heterogeneous data

Pack two arrays of different numeric kinds (real/real, real/integer, integer/integer) into a single byte stream before encoding, via the pack_data helper.

🧩

Fortran 2003+ Compliant

Fully standard-compliant library. Tested with GNU (≥ 4.9.2) and Intel (≥ 12.x) compilers.

🆓

Free & Open Source

Quick start

fortran

use befor64

call b64_init() ! initialise once

! encode a scalar real
character(len=:), allocatable :: code
call b64_encode(n=1.0_R8P, code=code)

! encode an integer array
call b64_encode(n=[12_I4P, 1_I4P], code=code)

! decode back
real(R8P) :: val
call b64_decode(code='AAAAAAAA8D8=', n=val)

b64_init must be called at the very beginning of encode/decode operations (just once). The flag is_b64_initialized can be checked at any time to confirm the library is ready.
