Certigo is a utility to examine and validate certificates in a variety of formats.
To install certigo, simply use:
go get -u github.com/square/certigo
Note that certigo requires Go 1.6 or later to build.
We use glide for managing vendored dependencies.
Certigo can read certificates/keystores in various formats and dump them to stdout.
Currently supported formats are DER, PEM, JCEKS/JKS and PKCS12. Certigo will display information in a human-readable way, and print warnings for common mistakes (such as small key sizes or weak signatures/hash functions). Certigo can also convert any input to a series of PEM blocks, which is useful if you want to e.g. dump the contents of PKCS12/JCEKS keystores into something more useful.
