Variables ¶
var AlwaysTimeWindow = NewMaintenanceTimeWindow(NewMaintenanceTime(0, 0, 0), NewMaintenanceTime(23, 59, 59))
AlwaysTimeWindow is a MaintenanceTimeWindow that contains all durations.
var ( // RandomFunc is a function that computes a random number. RandomFunc = rand.Int63nRange )
Functions ¶
func ComputeSHA1Hex ¶
ComputeSHA1Hex computes the hexadecimal representation of the SHA1 hash of the given input byte slice <in>, converts it to a string and returns it (length of returned string is 40 characters).
func ComputeSHA256Hex ¶
ComputeSHA256Hex computes the hexadecimal representation of the SHA256 hash of the given input byte slice <in>, converts it to a string and returns it.
func CreateSHA1Secret ¶
CreateSHA1Secret takes a username and a password and returns a sha1-schemed credentials pair as string.
func DecodeBase64 ¶
DecodeBase64 takes a Base64-encoded string and returns the decoded byte slice.
func DecodeCertificate ¶
func DecodeCertificate(bytes []byte) (*x509.Certificate, error)
DecodeCertificate takes a byte slice, decodes it from the PEM format, converts it to an x509.Certificate object, and returns it. In case an error occurs, it returns the error.
func DecodePrivateKey ¶
func DecodePrivateKey(bytes []byte) (*rsa.PrivateKey, error)
DecodePrivateKey takes a byte slice, decodes it from the PEM format, converts it to an rsa.PrivateKey object, and returns it. In case an error occurs, it returns the error.
func EncodeBase64 ¶
EncodeBase64 takes a byte slice and returns the Base64-encoded string.
func EncodeCertificate ¶
EncodeCertificate takes a certificate as a byte slice, encodes it to the PEM format, and returns it as byte slice.
func EncodePrivateKey ¶
func EncodePrivateKey(key *rsa.PrivateKey) []byte
EncodePrivateKey takes a RSA private key object, encodes it to the PEM format, and returns it as a byte slice.
func EncodePrivateKeyInPKCS8 ¶
func EncodePrivateKeyInPKCS8(key *rsa.PrivateKey) ([]byte, error)
EncodePrivateKeyInPKCS8 takes a RSA private key object, encodes it to the PKCS8 format, and returns it as a byte slice.
func EncodeSHA1 ¶
EncodeSHA1 takes a byte slice and returns the sha1-hashed string (base64-encoded).
func FindFreePort ¶
FindFreePort finds a free port on the host machine and returns it.
func GenerateRandomString ¶
GenerateRandomString uses crypto/rand to generate a random string of the specified length <n>. The set of allowed characters is [0-9a-zA-Z], thus no special characters are included in the output. Returns error if there was a problem during the random generation.
func GenerateRandomStringFromCharset ¶
GenerateRandomStringFromCharset generates a cryptographically secure random string of the specified length <n>. The set of allowed characters can be specified. Returns error if there was a problem during the random generation.
func HashForMap ¶
HashForMap creates a hash value for a map of type map[string]interface{} and returns it.
func MergeMaps ¶
MergeMaps takes two maps <a>, <b> and merges them. If <b> defines a value with a key already existing in the <a> map, the <a> value for that key will be overwritten.
func MergeStringMaps ¶
MergeStringMaps merges the content of the newMaps with the oldMap. If a key already exists then it gets overwritten by the last value with the same key.
func RenderLocalTemplate ¶
RenderLocalTemplate uses a template <tpl> given as a string and renders it. Thus, the template does not necessarily need to be stored as a file.
func RenderTemplate ¶
RenderTemplate reads the template file in the <templateDir> directory and renders it. It injects a bunch of standard functions which can be used in the template file.
func RenderTemplateWithFuncs ¶
func RenderTemplateWithFuncs(filename string, funcs template.FuncMap, values interface{}) ([]byte, error)
RenderTemplateWithFuncs reads the template file in the <templateDir> directory and renders it. It allows providing a user-defined template.FuncMap <funcs> to the template which will be merged with the standard functions and provided to the template file. The user-defined functions always take precedence in the merge process.
func RenderTemplatesWithFuncs ¶
func RenderTemplatesWithFuncs(filenames []string, funcs template.FuncMap, values interface{}) ([]byte, error)
RenderTemplatesWithFuncs does the same as RenderTemplateWithFuncs except that it allows providing multiple template files instead of only exactly one.
func TestEmail ¶
TestEmail validates the provided <email> against a regular expression and returns whether it matches.
func TimeElapsed ¶
TimeElapsed takes a <timestamp> and a <duration> checks whether the elapsed time until now is less than the <duration>. If yes, it returns true, otherwise it returns false.
func ValueExists ¶
ValueExists returns true or false, depending on whether the given string <value> is part of the given []string list <list>.
