• decode - used to decode a JWT into its component parts.
• verify - used to verify the signature of a JWT.

Examples of Common Use Cases

Pyjwt3 can be used in a number of different scenarios. Here are some examples of common use cases:

• Generating a JWT for authentication and authorization.
• Verifying the signature of an incoming JWT.
• Encoding data into a JWT for secure transmission.
• Decoding a JWT to access its component parts.

Advanced Options and Flags

Pyjwt3 also offers several advanced options and flags that can be used to customize the output or behavior of the command. Here are some of the available options and flags:

• -a - used to specify the algorithm used for signing the JWT.
• -t - used to specify the type of JWT (e.g. access token, refresh token, etc).

Troubleshooting Tips and Potential Errors

When using Pyjwt3, there are a few potential errors and troubleshooting tips to keep in mind. Here are some of the most common errors and tips:

• Ensure that the correct algorithm is specified when signing the JWT.
• Make sure that the secret used for signing the JWT is kept secure.
• Check that the expiration date of the JWT is set correctly.
• Ensure that the issuer of the JWT is specified correctly.
• Check that the version of the JWT is set correctly.
• Make sure that the JWT is properly encoded and decoded.
