GOUTILS
This is a collection of small utility code I've written in Go; the cmd/
directory has a number of command-line utilities. Rather than keep all
of these in superfluous repositories of their own, or rewriting them
for each project, I'm putting them here.
The project can be built with the standard Go tooling, or it can be built with Bazel.
Contents:
ahash/ Provides hashes from string algorithm specifiers.
assert/ Error handling, assertion-style.
backoff/ Implementation of an intelligent backoff strategy.
cmd/
atping/ Automated TCP ping, meant for putting in cronjobs.
certchain/ Display the certificate chain from a
TLS connection.
certdump/ Dump certificate information.
certexpiry/ Print a list of certificate subjects and expiry times
or warn about certificates expiring within a certain
window.
certverify/ Verify a TLS X.509 certificate, optionally printing
the time to expiry and checking for revocations.
clustersh/ Run commands or transfer files across multiple
servers via SSH.
cruntar/ Untar an archive with hard links, copying instead of
linking.
csrpubdump/ Dump the public key from an X.509 certificate request.
data_sync/ Sync the user's homedir to external storage.
diskimg/ Write a disk image to a device.
eig/ EEPROM image generator.
fragment/ Print a fragment of a file.
jlp/ JSON linter/prettifier.
kgz/ Custom gzip compressor / decompressor that handles 99%
of my use cases.
parts/ Simple parts database management for my collection of
electronic components.
pem2bin/ Dump the binary body of a PEM-encoded block.
pembody/ Print the body of a PEM certificate.
pemit/ Dump data to a PEM file.
readchain/ Print the common name for the certificates
in a bundle.
renfnv/ Rename a file to base32-encoded 64-bit FNV-1a hash.
rhash/ Compute the digest of remote files.
showimp/ List the external (e.g. non-stdlib and outside the
current working directory) imports for a Go file.
ski Display the SKI for PEM-encoded TLS material.
sprox/ Simple TCP proxy.
stealchain/ Dump the verified chain from a TLS
connection to a server.
stealchain- Dump the verified chain from a TLS
server/ connection from a client.
subjhash/ Print or match subject info from a certificate.
tlskeypair/ Check whether a TLS certificate and key file match.
utc/ Convert times to UTC.
yamll/ A small YAML linter.
config/ A simple global configuration system where configuration
data is pulled from a file or an environment variable
transparently.
dbg/ A debug printer.
die/ Death of a program.
fileutil/ Common file functions.
lib/ Commonly-useful functions for writing Go programs.
logging/ A logging library.
mwc/ MultiwriteCloser implementation.
rand/ Utilities for working with math/rand.
sbuf/ A byte buffer that can be wiped.
seekbuf/ A read-seekable byte buffer.
syslog/ Syslog-type logging.
tee/ Emulate tee(1)'s functionality in io.Writers.
testio/ Various I/O utilities useful during testing.
testutil/ Various utility functions useful during testing.
Each program should have a small README in the directory with more information.
