Functions

func GetRoot

func GetRoot(tree *merkletree.MerkleTree) []byte

GetRoot returns the Merkle root hash for a tree

func VerifyTree

func VerifyTree(tree *merkletree.MerkleTree) (bool, error)

Types

type Content

type Content struct {
	// contains filtered or unexported fields
}

Content implements merkletree.Content interface for CID-based content

func NewContent

func NewContent(cid string) Content

NewContent creates a new Content from a CID

func (Content) CalculateHash

func (c Content) CalculateHash() ([]byte, error)

CalculateHash implements the Content interface

func (Content) Equals

func (c Content) Equals(other merkletree.Content) (bool, error)

Equals implements the Content interface

type FileIntegrity

type FileIntegrity struct {
	FilePath   string   // Path to the file
	CIDs       []string // List of CIDs (chunks or diffs)
	MerkleRoot []byte   // Merkle root hash
	IsValid    bool     // Validation result
}

FileIntegrity represents the integrity information for a file

type MerkleManager

type MerkleManager struct {
	// contains filtered or unexported fields
}

MerkleManager manages Merkle trees for file integrity verification
