## Core types

### `Encryptable`

Factory for creating encryptable input items.

| Method | Input type | Solidity param |
| - | - | - |
| `Encryptable.bool(value)` | `boolean` | `externalEbool` |
| `Encryptable.uint8(value)` | `bigint \| string` | `externalEuint8` |
| `Encryptable.uint16(value)` | `bigint \| string` | `externalEuint16` |
| `Encryptable.uint32(value)` | `bigint \| string` | `externalEuint32` |
| `Encryptable.uint64(value)` | `bigint \| string` | `externalEuint64` |
| `Encryptable.uint128(value)` | `bigint \| string` | `externalEuint128` |
| `Encryptable.address(value)` | `bigint \| string` | `externalEaddress` |
| `Encryptable.create(type, value)` | varies | varies |

### `FheTypes`

Enum of supported FHE types used with `decryptForView`.

| Value | JS return type |
| - | - |
| `FheTypes.Bool` | `boolean` |
| `FheTypes.Uint8` | `bigint` |
| `FheTypes.Uint16` | `bigint` |
| `FheTypes.Uint32` | `bigint` |
| `FheTypes.Uint64` | `bigint` |
| `FheTypes.Uint128` | `bigint` |
| `FheTypes.Uint160` | `string` (checksummed address) |

### The `encryptInputs` result

`execute()` returns one ciphertext handle per input, in order, followed by a single signature covering the whole batch:

```typescript theme={null}
type EncryptInputsResult = readonly `0x${string}`[];
// [ ...hashes, signature ]  -> inputs.length + 1 elements
```

The per-item `EncryptedItemInput` struct and its typed variants were removed in `0.7`, along with `asHashPlusProof()`.

### `EncryptStep`

Enum values fired during the encryption pipeline:

| Value | Description |
| - | - |
| `EncryptStep.InitTfhe` | Initialize TFHE WASM module |
| `EncryptStep.FetchKeys` | Fetch FHE public key and CRS |
| `EncryptStep.Pack` | Pack plaintext values |
| `EncryptStep.Prove` | Generate ZK proof |
| `EncryptStep.Verify` | Submit to CoFHE verifier |
