Method DecryptDataSeek

backend/crypt/cipher.go:1112–1118

DecryptDataSeek decrypts the data stream from offset The open function must return a ReadCloser opened to the offset supplied. You must use this form of DecryptData if you might want to Seek the file handle

(ctx context.Context, open OpenRangeSeek, offset, limit int64)
