pemit
This is a utility to pem-encode data. It requires a PEM type to be
specified via the `-t` flag. Any number of files may be specified on
the command line; alternatively, if no arguments are provided or the
only argument is "-", pemit will read from standard input.
Example of standard input:
$ dd if=/dev/zero bs=32 count=1 | pemit -t "NULL DATA"
1+0 records in
1+0 records out
32 bytes (32 B) copied, 8.8908e-05 s, 360 kB/s
-----BEGIN NULL DATA-----
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
-----END NULL DATA-----
$ dd if=/dev/zero bs=32 count=1 | pemit -t "NULL DATA" -
1+0 records in
1+0 records out
32 bytes (32 B) copied, 3.1041e-05 s, 1.0 MB/s
-----BEGIN NULL DATA-----
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
-----END NULL DATA-----
Using files:
$ dd if=/dev/zero of=fileA bs=32 count=1
1+0 records in
1+0 records out
32 bytes (32 B) copied, 9.0908e-05 s, 352 kB/s
$ dd if=/dev/zero of=fileB bs=32 count=1
1+0 records in
1+0 records out
32 bytes (32 B) copied, 9.0908e-05 s, 352 kB/s
$ pemit -t NULL\ DATA fileA
-----BEGIN NULL DATA-----
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
-----END NULL DATA-----
$ pemit -t NULL\ DATA fileA fileB
-----BEGIN NULL DATA-----
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAA==
-----END NULL DATA-----
