func DecryptETag 

func DecryptETag(key crypto.ObjectKey, object ObjectInfo) (string, error)

DecryptETag decrypts the ETag that is part of given object with the given object encryption key.

However, DecryptETag does not try to decrypt the ETag if it consists of a 128 bit hex value (32 hex chars) and exactly one '-' followed by a 32-bit number. This special case adresses randomly-generated ETags generated by the MinIO server when running in non-compat mode. These random ETags are not encrypt.

Calling DecryptETag with a non-randomly generated ETag will fail.

func DecryptObjectInfo

It fails if the object is encrypted and the HTTP headers don't contain SSE-C headers or the object is not encrypted but SSE-C headers are provided. (AWS behavior) DecryptObjectInfo returns 'ErrNone' if the object is not encrypted or the decryption succeeded.

DecryptObjectInfo also returns whether the object is encrypted or not.

type WebGenericRep 

type WebGenericRep struct {
	UIVersion string `json:"uiVersion"`

type WebIdentityResult 

type WebIdentityResult struct {
	// The identifiers for the temporary security credentials that the operation
	// returns.
	AssumedRoleUser AssumedRoleUser `xml:",omitempty"`

	// The intended audience (also known as client ID) of the web identity token.
	// This is traditionally the client identifier issued to the application that
	// requested the client grants.
	Audience string `xml:",omitempty"`

	// The temporary security credentials, which include an access key ID, a secret
	// access key, and a security (or session) token.
	//
	// Note: The size of the security token that STS APIs return is not fixed. We
	// strongly recommend that you make no assumptions about the maximum size. As
	// of this writing, the typical size is less than 4096 bytes, but that can vary.
	// Also, future updates to AWS might require larger sizes.
	Credentials auth.Credentials `xml:",omitempty"`

	// A percentage value that indicates the size of the policy in packed form.
	// The service rejects any policy with a packed size greater than 100 percent,
	// which means the policy exceeded the allowed space.
	PackedPolicySize int `xml:",omitempty"`

	// The issuing authority of the web identity token presented. For OpenID Connect
	// ID tokens, this contains the value of the iss field. For OAuth 2.0 access tokens,
	// this contains the value of the ProviderId parameter that was passed in the
	// AssumeRoleWithWebIdentity request.
	Provider string `xml:",omitempty"`

	// The unique user identifier that is returned by the identity provider.
	// This identifier is associated with the Token that was submitted
	// with the AssumeRoleWithWebIdentity call. The identifier is typically unique to
	// the user and the application that acquired the WebIdentityToken (pairwise identifier).
	// For OpenID Connect ID tokens, this field contains the value returned by the identity
	// provider as the token's sub (Subject) claim.
	SubjectFromWebIdentityToken string `xml:",omitempty"`
}

WebIdentityResult - Contains the response to a successful AssumeRoleWithWebIdentity request, including temporary credentials that can be used to make MinIO API requests.

type WebObjectInfo 

type WebObjectInfo struct {
	// Name of the object
	Key string `json:"name"`
	// Date and time the object was last modified.
	LastModified time.Time `json:"lastModified"`

	Size int64 `json:"size"`
	// ContentType is mime type of the object.
	ContentType string `json:"contentType"`
}

WebObjectInfo container for list objects metadata.
