SIMPLE_BASE64

Creation

Initialize the encoder. No parameters required.

encode (a_input: STRING): STRING

Encode a string to standard Base64 with padding.

encode_bytes (a_bytes: ARRAY [NATURAL_8]): STRING

Encode a byte array to standard Base64. Useful for binary data.

encode_url (a_input: STRING): STRING

Encode to URL-safe Base64URL without padding. Uses - and _ instead of + and /.

encode_url_with_padding (a_input: STRING): STRING

Encode to URL-safe Base64URL with padding preserved.

decode (a_input: STRING): STRING

Decode a Base64 or Base64URL string back to the original string.

decode_bytes (a_input: STRING): ARRAY [NATURAL_8]

Decode Base64 to a byte array. Automatically handles both standard and URL-safe formats.

decode_url (a_input: STRING): STRING

Decode a URL-safe Base64URL string. Alias for decode with clearer intent.

is_valid_base64 (a_string: STRING): BOOLEAN

Check if a string is valid standard Base64 (with proper length and characters).

Format: Length must be a multiple of 4. Characters must be A-Z, a-z, 0-9, +, /, or = (padding).

is_valid_base64_url (a_string: STRING): BOOLEAN

Check if a string is valid URL-safe Base64URL.

Characters must be A-Z, a-z, 0-9, -, _, or = (padding). Length does not need to be a multiple of 4.

to_url_safe (a_base64: STRING): STRING

Convert standard Base64 to URL-safe format. Replaces + with - and / with _.

to_standard (a_base64url: STRING): STRING

Convert URL-safe Base64URL to standard format. Replaces - with + and _ with /.
