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, I'm putting them here.
Contents:
ahash/ Provides hashes from string algorithm specifiers.
assert/ Error handling, assertion-style.
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.
fragment/ Print a fragment of a file.
jlp/ JSON linter/prettifier.
kgz/ Custom gzip compressor / decompressor that handles 99%
of my use cases.
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.
showimp/ List the external (e.g. non-stdlib and outside the
current working directory) imports for a Go 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 Display the external imports in a package.
ski Display the SKI for PEM-encoded TLS material.
stealchain/ Dump the verified chain from a TLS
connection.
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.
die/ Death of a program.
fileutil/ Common file functions.
lib/ Commonly-useful functions for writing Go programs.
logging/ A logging library.
mwc/ MultiwriteCloser implementation.
sbuf/ A byte buffer that can be wiped.
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.
