Functions

func DumpPEM

func DumpPEM(data []byte, header string) string

DumpPEM transforms block to pem-encoding.

Reverse of ParsePEM.

func ParsePEM

func ParsePEM(data, header string) ([]byte, error)

ParsePEM takes pem-encoded block and decodes it, checking the header.

func SerializeSN

func SerializeSN(sn *big.Int) ([]byte, error)

SerializeSN converts a certificate serial number to a byte blob.

func ServiceVersion

func ServiceVersion(c context.Context, s signing.Signer) (string, error)

ServiceVersion returns a string that identifies the app and the version.

It is put in some server responses. The function extracts this information from the given signer.

This function almost never returns errors. It can return an error only when called for the first time during the process lifetime. It gets cached after first successful return.

func TokenFingerprint

func TokenFingerprint(tok string) string

TokenFingerprint returns first 16 bytes of SHA256 of the token, as hex.

Token fingerprints can be used to identify tokens without parsing them.

func ZlibCompress

func ZlibCompress(in []byte) ([]byte, error)

ZlibCompress zips a blob using zlib.

func ZlibDecompress

func ZlibDecompress(in []byte) ([]byte, error)

ZlibDecompress unzips a blob using zlib.
