Encodes a base64 string from a bytes array.

base64_encode_fromarray(base64_string_decoded_as_a_byte_array)

Returns the base64 string encoded from the bytes array. Note that byte is an integer type.

let bytes_array = toscalar(print base64_decode_toarray("S3VzdG8="));
print decoded_base64_string = base64_encode_fromarray(bytes_array)

Output

Trying to encode a base64 string from an invalid bytes array that was generated from invalid UTF-8 encoded string will return null:

let empty_bytes_array = toscalar(print base64_decode_toarray("U3RyaW5n0KHR0tGA0L7Rh9C60LA"));
print empty_string = base64_encode_fromarray(empty_bytes_array)

Output

• For decoding base64 strings to a UTF-8 string, see base64_decode_tostring()
• For encoding strings to a base64 string see base64_encode_tostring()
• This function is the inverse of base64_decode_toarray()
