Will Boxcryptor Portable work on Linux on ARM 64 bit processors?

When I tried to run on a Debian Linux ARM 32 bit variant the error thrown was:
./Boxcryptor_Portable.sh: line 6: ./../runtime/bin/java: cannot execute binary file: Exec format error
Filesystem doesn't support native execution, starting fallback procedure
./Boxcryptor_Portable.sh: line 32: /lib64/ld-linux-x86-64.so.2: No such file or directory

I then read on a different forum thread there was mention of:

• only 64 bit processors are supported and
• for linux non FAT32 filesystems (for the native executable flag)

but as then as the binary filename includes x86-64 seems to imply only x86 processor architecture is supported for Linux. Is that the case?

If so, could the portable version also be compiled for ARM 64 architecture?

Thanks.
