Functions ¶

func AuthHeaderValue ¶

func AuthHeaderValue(signature, accessKey, credentialScope, signedHeaders string) string

Get the finalized value for the "Authorization" header. The signature parameter is the output from SignStringToSign

func CanonicalRequest ¶

func CanonicalRequest(r *http.Request, signedHeaders map[string]bool) (string, error)

Build a CanonicalRequest from a regular request string

See http://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html CanonicalRequest =

HTTPRequestMethod + '\n' +
CanonicalURI + '\n' +
CanonicalQueryString + '\n' +
CanonicalHeaders + '\n' +
SignedHeaders + '\n' +
HexEncode(Hash(RequestPayload))

func CredentialScope ¶

func CredentialScope(t time.Time, regionName, serviceName string) string

Return the Credential Scope. See http://docs.aws.amazon.com/general/latest/gr/sigv4-create-string-to-sign.html

func GenerateSigningKey ¶

func GenerateSigningKey(secretKey, regionName, serviceName string, t time.Time) ([]byte, error)

Generate a "signing key" to sign the "String To Sign". See http://docs.aws.amazon.com/general/latest/gr/sigv4-calculate-signature.html

func HexEncodeSHA256Hash ¶

func HexEncodeSHA256Hash(body []byte) (string, error)

HexEncodeSHA256Hash return hexcode of sha256

func SignStringToSign ¶

func SignStringToSign(stringToSign string, signingKey []byte) (string, error)

Create the AWS Signature Version 4. See http://docs.aws.amazon.com/general/latest/gr/sigv4-calculate-signature.html

func StringToSign ¶

func StringToSign(canonicalRequest, credentialScope string, t time.Time) string

Create a "String to Sign". See http://docs.aws.amazon.com/general/latest/gr/sigv4-create-string-to-sign.html

Types ¶

func GetSignature ¶

func GetSignature(r *http.Request) (*Signature, string, map[string]bool, error)
