AWS Encryption SDK for Javascript examples in a browser
The AWS Encryption SDK for JavaScript is a client-side encryption library designed to make it easy for everyone to encrypt and decrypt data using industry standards and best practices. It uses a data format compatible with the AWS Encryption SDKs in other languages. For more information on the AWS Encryption SDKs in all languages, see the Developer Guide.
The CMKs in these examples are only for example. Replace these CMKs with your own.
About example-browser
This repository holds examples for encrypting and decrypting in a browser. These are not for production use.
This package is intended to act as a working example. It is not intended for direct use by clients. To get started with the AWS Encryption SDK for JavaScript, follow the instructions in the README.
KMS Simple Example
This is a simple example of using a KMS keyring to encrypt and decrypt using the AWS Encryption SDK for Javascript in a browser. For more information, see kms_simple.ts.
RSA Simple Example
This is an example of using a RSA key pair to encrypt and decrypt a simple string. This has some advantages for certain use cases, but we recommend that you use a keyring that protects your wrapping keys and performs cryptographic operations within a secure boundary. The KMS keyring uses AWS Key Management Service (AWS KMS) customer master keys (CMKs) that never leave AWS KMS unencrypted. For a more detailed explanation, see rsa_simple.ts.
AES Simple Example
This is an example of using a shared secret to encrypt and decrypt a simple string. This has some advantages for certain use cases, but we recommend that you use a keyring that protects your wrapping keys and performs cryptographic operations within a secure boundary. The KMS keyring uses AWS Key Management Service (AWS KMS) customer master keys (CMKs) that never leave AWS KMS unencrypted. For a more detailed explanation, see aes_simple.ts.
Multi keyring Example
This is a simple example of combining an KMS keyring and a raw AES keyring to encrypt and decrypt using the AWS Encryption SDK for Javascript in a browser. This has some advantages for certain use cases, but we recommend that you use a keyring that protects your wrapping keys and performs cryptographic operations within a secure boundary. The KMS keyring uses AWS Key Management Service (AWS KMS) customer master keys (CMKs) that never leave AWS KMS unencrypted. For a more detailed explanation, see multi_keyring.ts.
