Summary: Wrong RSA encryption

Initial Comment:
A big file is split up in chunks smaller than
((size()+1)/8 - 11).
The modules contains 64 bytes so a chunk is 53 bytes.
In front I add 0x00 0x02 PS 0x00 (the PKCS1 standard?).
PS is pseudo non zero random padding of at least 8 bytes.
Sometimes (seems irregular) encrypt() returns 63 bytes.
64 bytes are expected. 
Then I call encrypt() again for the same data. 
This second time the correct 64 bytes are returned.
