Functions

a2b_base64

a2b_base64(data, /)

  Decode a line of base64 data.

a2b_hex

a2b_hex(hexstr, /)

  Binary data of hexadecimal representation.

  hexstr must contain an even number of hex digits (upper or lower case).
  This function is also available as "unhexlify()".

a2b_hqx

a2b_hqx(data, /)

  Decode .hqx coding.

a2b_qp

a2b_qp(data, header=False)

  Decode a string of qp-encoded data.

a2b_uu

a2b_uu(data, /)

  Decode a line of uuencoded data.

b2a_base64

b2a_base64(data, /, *, newline=True)

  Base64-code line of data.

b2a_hex

b2a_hex(...)

  Hexadecimal representation of binary data.

    sep
      An optional single character or byte to separate hex bytes.
    bytes_per_sep
      How many bytes between separators.  Positive values count from the
      right, negative values count from the left.

  The return value is a bytes object.  This function is also
  available as "hexlify()".

  Example:
  >>> binascii.b2a_hex(b'\xb9\x01\xef')
  b'b901ef'
  >>> binascii.hexlify(b'\xb9\x01\xef', ':')
  b'b9:01:ef'
  >>> binascii.b2a_hex(b'\xb9\x01\xef', b'_', 2)
  b'b9_01ef'

b2a_hqx

b2a_hqx(data, /)

  Encode .hqx data.

b2a_qp

b2a_qp(data, quotetabs=False, istext=True, header=False)

  Encode a string using quoted-printable encoding.

  On encoding, when istext is set, newlines are not encoded, and white
  space at end of lines is.  When istext is not set, \r and \n (CR/LF)
  are both encoded.  When quotetabs is set, space and tabs are encoded.

b2a_uu

b2a_uu(data, /, *, backtick=False)

  Uuencode line of data.

crc32

crc32(data, crc=0, /)

  Compute CRC-32 incrementally.

crc_hqx

crc_hqx(data, crc, /)

  Compute CRC-CCITT incrementally.

hexlify

hexlify(...)

  Hexadecimal representation of binary data.

    sep
      An optional single character or byte to separate hex bytes.
    bytes_per_sep
      How many bytes between separators.  Positive values count from the
      right, negative values count from the left.

  The return value is a bytes object.  This function is also
  available as "b2a_hex()".

rlecode_hqx

rlecode_hqx(data, /)

  Binhex RLE-code binary data.

rledecode_hqx

rledecode_hqx(data, /)

  Decode hexbin RLE-coded string.

unhexlify

unhexlify(hexstr, /)

  Binary data of hexadecimal representation.

  hexstr must contain an even number of hex digits (upper or lower case).
