**podman image import** [*options*] *path* [*reference*]
## DESCRIPTION
**podman import** imports a tarball (.tar, .tar.gz, .tgz)
**podman import** imports a tarball (possibly compressed using Gzip, Bzip2, XZ or Zstd)
and saves it as a filesystem image. Remote tarballs can be specified using a URL.
Various image instructions can be configured with the **--change** flag and
a commit message can be set using the **--message** flag.

# v4.0.1
## Fixed
- An attacker could send a JWE containing compressed data that used large
amounts of memory and CPU when decompressed by `Decrypt` or `DecryptMulti`.
Those functions now return an error if the decompressed data would exceed
250kB or 10x the compressed size (whichever is larger). Thanks to
Enze Wang@Alioth and Jianjun Chen@Zhongguancun Lab (@zer0yu and @chenjj)
for reporting.
# v4.0.0
This release makes some breaking changes in order to more thoroughly
address the vulnerabilities discussed in [Three New Attacks Against JSON Web
Tokens][1], "Sign/encrypt confusion", "Billion hash attack", and "Polyglot
token".
## Changed
- Limit JWT encryption types (exclude password or public key types) (#78)
- Enforce minimum length for HMAC keys (#85)
- jwt: match any audience in a list, rather than requiring all audiences (#81)
- jwt: accept only Compact Serialization (#75)
- jws: Add expected algorithms for signatures (#74)
- Require specifying expected algorithms for ParseEncrypted,
ParseSigned, ParseDetached, jwt.ParseEncrypted, jwt.ParseSigned,
jwt.ParseSignedAndEncrypted (#69, #74)
- Usually there is a small, known set of appropriate algorithms for a program
to use and it's a mistake to allow unexpected algorithms. For instance the
"billion hash attack" relies in part on programs accepting the PBES2
encryption algorithm and doing the necessary work even if they weren't
specifically configured to allow PBES2.
- Revert "Strip padding off base64 strings" (#82)
- The specs require base64url encoding without padding.
- Minimum supported Go version is now 1.21
## Added
- ParseSignedCompact, ParseSignedJSON, ParseEncryptedCompact, ParseEncryptedJSON.
- These allow parsing a specific serialization, as opposed to ParseSigned and
ParseEncrypted, which try to automatically detect which serialization was
provided. It's common to require a specific serialization for a specific
protocol - for instance JWT requires Compact serialization.
[1]: https://i.blackhat.com/BH-US-23/Presentations/US-23-Tervoort-Three-New-Attacks-Against-JSON-Web-Tokens.pdf
# v3.0.3
## Fixed
- Limit decompression output size to prevent a DoS. Backport from v4.0.1.
# v3.0.2
## Fixed
- DecryptMulti: handle decompression error (#19)
## Changed
- jwe/CompactSerialize: improve performance (#67)
- Increase the default number of PBKDF2 iterations to 600k (#48)
- Return the proper algorithm for ECDSA keys (#45)
## Added
- Add Thumbprint support for opaque signers (#38)
# v3.0.1
## Fixed
- Security issue: an attacker specifying a large "p2c" value can cause
JSONWebEncryption.Decrypt and JSONWebEncryption.DecryptMulti to consume large
amounts of CPU, causing a DoS. Thanks to Matt Schwager (@mschwager) for the
disclosure and to Tom Tervoort for originally publishing the category of attack.

# Go JOSE
### Versions
[Version 4](https://github.com/go-jose/go-jose)
([branch](https://github.com/go-jose/go-jose/),
[doc](https://pkg.go.dev/github.com/go-jose/go-jose/v4), [releases](https://github.com/go-jose/go-jose/releases)) is the current stable version:
import "github.com/go-jose/go-jose/v4"
The old [square/go-jose](https://github.com/square/go-jose) repo contains the prior v1 and v2 versions, which
are deprecated.
### Summary
Package jose aims to provide an implementation of the Javascript Object Signing
and Encryption set of standards. This includes support for JSON Web Encryption,
JSON Web Signature, and JSON Web Token standards.
**Disclaimer**: This library contains encryption software that is subject to
the U.S. Export Administration Regulations. You may not export, re-export,
transfer or download this code or any part of it in violation of any United
States law, directive or regulation. In particular this software may not be
exported or re-exported in any form or on any media to Iran, North Sudan,
Syria, Cuba, or North Korea, or to denied persons or entities mentioned on any
US maintained blocked list.
## Overview
The implementation follows the
[JSON Web Encryption](https://dx.doi.org/10.17487/RFC7516) (RFC 7516),
[JSON Web Signature](https://dx.doi.org/10.17487/RFC7515) (RFC 7515), and
[JSON Web Token](https://dx.doi.org/10.17487/RFC7519) (RFC 7519) specifications.
Tables of supported algorithms are shown below. The library supports both
the compact and JWS/JWE JSON Serialization formats, and has optional support for
multiple recipients. It also comes with a small command-line utility
([`jose-util`](https://pkg.go.dev/github.com/go-jose/go-jose/jose-util))
for dealing with JOSE messages in a shell.
**Note**: We use a forked version of the `encoding/json` package from the Go
standard library which uses case-sensitive matching for member names (instead
of [case-insensitive matching](https://www.ietf.org/mail-archive/web/json/current/msg03763.html)).
This is to avoid differences in interpretation of messages between go-jose and
libraries in other languages.
### Supported algorithms
See below for a table of supported algorithms. Algorithm identifiers match
the names in the [JSON Web Algorithms](https://dx.doi.org/10.17487/RFC7518)
standard where possible. The Godoc reference has a list of constants.
Key encryption | Algorithm identifier(s)
:------------------------- | :------------------------------
RSA-PKCS#1v1.5 | RSA1_5
RSA-OAEP | RSA-OAEP, RSA-OAEP-256
AES key wrap | A128KW, A192KW, A256KW
AES-GCM key wrap | A128GCMKW, A192GCMKW, A256GCMKW
ECDH-ES + AES key wrap | ECDH-ES+A128KW, ECDH-ES+A192KW, ECDH-ES+A256KW
ECDH-ES (direct) | ECDH-ES<sup>1</sup>
Direct encryption | dir<sup>1</sup>
<sup>1. Not supported in multi-recipient mode</sup>
Signing / MAC | Algorithm identifier(s)
:------------------------- | :------------------------------
RSASSA-PKCS#1v1.5 | RS256, RS384, RS512
RSASSA-PSS | PS256, PS384, PS512
HMAC | HS256, HS384, HS512
ECDSA | ES256, ES384, ES512
Ed25519 | EdDSA<sup>2</sup>
<sup>2. Only available in version 2 of the package</sup>
Content encryption | Algorithm identifier(s)
:------------------------- | :------------------------------
AES-CBC+HMAC | A128CBC-HS256, A192CBC-HS384, A256CBC-HS512
AES-GCM | A128GCM, A192GCM, A256GCM
Compression | Algorithm identifiers(s)
:------------------------- | -------------------------------
DEFLATE (RFC 1951) | DEF
### Supported key types
See below for a table of supported key types. These are understood by the
library, and can be passed to corresponding functions such as `NewEncrypter` or
`NewSigner`. Each of these keys can also be wrapped in a JWK if desired, which
allows attaching a key id.
Algorithm(s) | Corresponding types
:------------------------- | -------------------------------
RSA | *[rsa.PublicKey](https://pkg.go.dev/crypto/rsa/#PublicKey), *[rsa.PrivateKey](https://pkg.go.dev/crypto/rsa/#PrivateKey)
ECDH, ECDSA | *[ecdsa.PublicKey](https://pkg.go.dev/crypto/ecdsa/#PublicKey), *[ecdsa.PrivateKey](https://pkg.go.dev/crypto/ecdsa/#PrivateKey)
EdDSA<sup>1</sup> | [ed25519.PublicKey](https://pkg.go.dev/crypto/ed25519#PublicKey), [ed25519.PrivateKey](https://pkg.go.dev/crypto/ed25519#PrivateKey)
AES, HMAC | []byte
<sup>1. Only available in version 2 or later of the package</sup>
## Examples

[![godoc](https://pkg.go.dev/badge/github.com/go-jose/go-jose/v3/jwt.svg)](https://pkg.go.dev/github.com/go-jose/go-jose/v3/jwt)
Examples can be found in the Godoc
reference for this package. The
[`jose-util`](https://github.com/go-jose/go-jose/tree/v3/jose-util)
subdirectory also contains a small command-line utility which might be useful
as an example as well.

# Safe JSON
This repository contains a fork of the `encoding/json` package from Go 1.6.
The following changes were made:
* Object deserialization uses case-sensitive member name matching instead of
[case-insensitive matching](https://www.ietf.org/mail-archive/web/json/current/msg03763.html).
This is to avoid differences in the interpretation of JOSE messages between
go-jose and libraries written in other languages.
* When deserializing a JSON object, we check for duplicate keys and reject the
input whenever we detect a duplicate. Rather than trying to work with malformed
data, we prefer to reject it right away.

# Contributing to go.opentelemetry.io/auto/sdk
The `go.opentelemetry.io/auto/sdk` module is a purpose built OpenTelemetry SDK.
It is designed to be:
0. An OpenTelemetry compliant SDK
1. Instrumented by auto-instrumentation (serializable into OTLP JSON)
2. Lightweight
3. User-friendly
These design choices are listed in the order of their importance.
The primary design goal of this module is to be an OpenTelemetry SDK.
This means that it needs to implement the Go APIs found in `go.opentelemetry.io/otel`.
Having met the requirement of SDK compliance, this module needs to provide code that the `go.opentelemetry.io/auto` module can instrument.
The chosen approach to meet this goal is to ensure the telemetry from the SDK is serializable into JSON encoded OTLP.
This ensures then that the serialized form is compatible with other OpenTelemetry systems, and the auto-instrumentation can use these systems to deserialize any telemetry it is sent.
Outside of these first two goals, the intended use becomes relevant.
This package is intended to be used in the `go.opentelemetry.io/otel` global API as a default when the auto-instrumentation is running.
Because of this, this package needs to not add unnecessary dependencies to that API.
Ideally, it adds none.
It also needs to operate efficiently.
Finally, this module is designed to be user-friendly to Go development.
It hides complexity in order to provide simpler APIs when the previous goals can all still be met.
