decrypted$\_$block $=$ 'None'

if len$($decrypted$\_$block$)<mn\; id="EditorElement\_97175">1</mn>$ :

# FIXME: If the decrypted block contains less digits

# than the block size L$,$ prepend the block with

# enough $\text{'}$s so that the numeric value of the block

# remains the same, but the new block size is $L,$

# e$.$g$.$ if $L=4$ and decrypted block is $\text{'}19\text{'}$ then prepend

# two $\text{'}$s to obtain $\text{'}0019\text{'}$

decrypted$\_$block $=$ None

# FIXME: Use

util.py to append to text the decrypted block

# transformed into Letters
