DESCRIPTION

       BaseZ  encodes/decodes  base16, base32, base32hex, base64 or base64url data stream per RFC
       4648; MIME base64 Content-Transfer-Encoding per RFC 2045; or PEM  Printable  Encoding  per
       RFC 1421.

       Base16  encoding  produces  a  multiple  of  two-character  blocks in hexadecimal notation
       [0-9a-f]. It needs no padding and preserves the sort order of the encoded  data.  Decoding
       is case insensitive.

       Base32  encoded  stream  is a multiple of eight-character blocks consisting of letters and
       numbers [A-Z2-7]. Numbers easily confused with some letters are skipped  intentionally  to
       make  this  encoding  suitable  for  storage on -- or transport over -- any medium or data
       transport mechanism, including non-case-preserving barcodes or printed  out  strings  that
       could  be  spelled out and typed in by humans. If needed, the last encoded block is padded
       with equal sign end padding. Appearance of the padding character [=] at  the  end  of  the
       encoded  steam  can be avoided by encoding data of size divisible by 5. Base32 decoding is
       case insensitive.

       Base32hex encoding works the same way as base32  but  witn  an  alternative  character-set
       [0-9a-v]  to  preserve  the encoded data sort order.  This encoding should not be confused
       with base32.

       Base64 encoded stream is a multiple of  four-character  blocks  using  uppercase  letters,
       lowercase  letters,  numbers, plus and slash [A-Za-z0-9+/]. It uses equal sign [=] for end
       padding. Base64 decoding is case sensitive. It has an option to convert local native  text
       line  breaks  into canonical CRLF sequences prior to encoding or to convert CRLF sequences
       into native text line breaks after the decoding.

       Base64url encoding is technically the same as base64 but instead of  the  plus  and  slash
       signs  [+/]  it uses minus and underscore [-_]. Appearance of the padding character [=] in
       the encoded stream can be avoided by encoding data of size divisible by 3.

       Base64mime and base64pem are the same encodes as  base64  but  with  encoded  stream  line
       length  limit  of  76  and  64 characters respectively. PEM decoding ignores all white and
       non-printable characters; MIME decoding ignores  all  characters  outside  of  the  encode
       character-set.

OPTIONS

       When  no  FILE  is  specified  or  when  FILE  is  -,  read standard input.  When multiple
       conflicting options appear, the last option wins.

       -d, -D, --decode
              Decode.  By default  ignore  the  space  and  newline  characters.   The  --strict,
              --ignore-all-space,  and  --ignore-garbage  options  provide alternative behaviors.
              Default option for unhex command.

       -r, --strict
              Do not ignore any characters outside of the encode character-set on decoding.

       -s, --ignore-all-space
              Ignore all white and  non-printable  ASCII  characters  on  decoding.  Default  for
              base64pem decoding.

       -g, --ignore-garbage
              Ignore  all characters outside of the encode character-set on decoding. Default for
              base64mime decoding.

       -x, --hex, --base16
              Base16 coding. Default for base16, hex and unhex commands.

       -j, --base32
              Base32 coding. Default for base32 and base32plain commands.

       -e  --base32hex
              Base32hex coding. Default for base32hex command.

       -c, --capitals, --upper-case
              Output upper case letters on encoding, if applicable.

       -l, --lower-case
              Output lower case letters on encoding, if applicable.

       -a, --base64
              Base64 coding. Default for basez, base64 and base64plain commands.

       -u, --base64url
              Base64url coding. Default for base64url command.

       -p, --base64pem
              PEM printable coding. Default for base64pem command.

       -m, --base64mime
              MIME base64 coding. Default for base64mime command.

       -t, --text
              Convert native text line breaks into CRLF sequences prior to  encoding  or  convert
              CRLF  sequences into native text line breaks after decoding. This option applies to
              all variants of base64 codings.

       -w N, -b N, --wrap=N, --break=N
              Set encoded stream line length limit to N characters.  The default value is 76  for
              base64mime  encode,  64  for  base64pem encode, infinity for all other encodes.  To
              disable any appearance of EOL characters in the encoded stream, set to 0.

       -i FILEIN, --input=FILEIN
              Input file. Default is standard input.  When FILEIN is -, read stdin.

       -o FILEOUT, --output=FILEOUT
              Output file. Default is standard output.  When FILEOUT is -, write to stdout.

       -h, --help
              Display help.

       --version
              Display program version information.

EXAMPLES

              echo 4a6f650a | hex --decode

       Inspect output of a command:

              echo Joe | hex --wrap 2

       Base32 encode a string:

              printf "Hi People\n" | base32plain

       MIME base64 encode a binary file to stdout per RFC 2045:

              base64mime FILE

       MIME base64 encode a text file to stdout per RFC 2045:

              base64mime --text FILE

       Base64 encode a file per RFC 4648

              base64plain FILE > base64.rfc4648.file
