BaseEncode

BaseEncode[ba]

encodes the byte array ba as a Base64 string.

BaseEncode[ba,"encoding"]

encodes using the specified encoding.

Details

  • In BaseEncode[ba], ba should be a ByteArray object.
  • Available encodings include:
  • "Base16"hexadecimal representation of byte values
    "Base64"default Base64 as described in the internet standard recommendation RFC 4648
    "Base85ASCII"Ascii85 or a85 encoding, with the "z shortcut"

Basic Examples  (2)

Encode a byte array:

Encode a byte array using the Ascii85 encoding:

Scope  (2)

Encode the bytes 1 through 12:

The bytes can be recovered using BaseDecode:

Convert byte values to hexadecimal pairs:

Properties & Relations  (10)

The default encoding is "Base64":

The string returned by BaseEncode[ba] and BaseEncode[ba,"Base64"] has length divisible by 4:

Padding will be added, if necessary:

The "Base16" format uses two characters for each byte value:

"Base64" encodes up to three bytes in each block of four characters:

"Base85ASCII" can encode four bytes in a block of five characters:

There is no padding to yield a complete block:

As a special rule, "Base85ASCII" will encode four consecutive zero bytes using the single character z:

BaseEncode is the inverse of BaseDecode:

BaseEncode encodes binary data as a Base64 string:

The export format "Base64" encodes the string representation of an expression converted to bytes:

Achieve the same result with BaseEncode, ToString and ByteArrayToString:

BaseEncode converts a sequence of bytes to a sequence of characters:

IntegerString converts integers to a base-64 representation using the alphabet of Base64:

BaseEncode converts the "ByteArray" format of Hash to its "Base64Encoding" format:

ByteArray uses Base64 encoding of its data in InputForm:
