f_base_enc()

t_slv_arr f_base_enc (   data in t_slv_arr ,   alphabet in t_base_alphabet   )

Function

Base encode data.

Parameters

data	Data array (8bit)
alphabet	Alphabet to use

Returns

Encoded data

Encode data according to RFC 4648 with the selected alphabet.

Example use

encoded_data := f_base_enc(data_8bit, BASE64);

f_base_enc_len()

natural f_base_enc_len (   data in t_slv_arr ,   alphabet in t_base_alphabet   )

Function

Get base encoded data length.

Parameters

data	Data array (8bit)
alphabet	Alphabet to use

Returns

Encoded data length

Get length of encoded data after applying RFC 4648 with the selected alphabet.

Example use

v_len := f_base_enc_len(data_8bit, BASE64);

f_base_dec()

t_slv_arr f_base_dec (   data in t_slv_arr ,   alphabet in t_base_alphabet   )

Function

Base decode data.

Parameters

data	Data array (8bit)
alphabet	Alphabet to use

Returns

Decoded data

Decode data according to RFC 4648 with the selected alphabet.

Example use

decoded_data := f_base_dec(data_8bit, BASE64);

f_base_dec_len()

natural f_base_dec_len (   data in t_slv_arr ,   alphabet in t_base_alphabet   )

Function

Get base decoded data length.

Parameters

data	Data array (8bit)
alphabet	Alphabet to use

Returns

Decoded data length

Get length of decoded data after applying RFC 4648 with the selected alphabet.

Example use

v_len := f_base_dec_len(data_8bit, BASE32HEX);
