+The EVP encode routines provide a high-level interface to base 64 encoding and
decoding. Base 64 encoding converts binary data into a printable form that uses
the characters A-Z, a-z, 0-9, "+" and "/" to represent the data. For every 3
bytes of binary data provided 4 bytes of base 64 encoded data will be produced
be encoded or decoded that are pending in the B<ctx> object.
EVP_EncodeBlock() encodes a full block of input data in B<f> and of length
-B<dlen> and stores it in B<t>. For every 3 bytes of input provided 4 bytes of
-output data will be produced. If B<dlen> is not divisible by 3 then the block is
+B<n> and stores it in B<t>. For every 3 bytes of input provided 4 bytes of
+output data will be produced. If B<n> is not divisible by 3 then the block is
encoded as a final block of data and the output is padded such that it is always
divisible by 4. Additionally a NUL terminator character will be added. For
example if 16 bytes of input data is provided then 24 bytes of encoded data is
