step crypto jwe encrypt – encrypt a payload using JSON Web Encryption (JWE)
step crypto jwe encrypt
step crypto jwe encrypt encrypts a payload using JSON Web Encryption (JWE). By default, the payload to encrypt is read from STDIN and the JWE data structure will be written to STDOUT.
For examples, see step help crypto jwe.
- The cryptographic algorithm used to encrypt or determine the value of the content encryption key (CEK). Algorithms are case-sensitive strings defined in RFC7518. The selected algorithm must be compatible with the key type. This flag is optional. If not specified, the “alg” member of the JWK is used. If the JWK has no “alg” member then a default is selected depending on the JWK key type. If the JWK has an “alg” member and the –alg flag is passed the two options must match unless the –subtle flag is also passed.
key-enc-algorithmis a case-sensitive string and must be one of:
- RSAES OAEP using default parameters
- RSA-OAEP-256 (default for RSA keys)
- RSAES OAEP using SHA-256 and MGF1 with SHA-256
- AES Key Wrap with default initial value using 128-bit key
- AES Key Wrap with default initial value using 192-bit key
- AES Key Wrap with default initial value using 256-bit key
- Direct use of a shared symmetric key as the content encryption key (CEK)
- ECDH-ES (default for EC keys)
- Elliptic Curve Diffie-Hellman Ephemeral Static key agreement
- ECDH-ES using Concat KDF and CEK wrapped with “A128KW
- ECDH-ES using Concat KDF and CEK wrapped with “A192KW
- ECDH-ES using Concat KDF and CEK wrapped with “A256KW
- Key wrappiung with AES GCM using 128-bit key
- Key wrappiung with AES GCM using 192-bit key
- A256GCMKW (default for oct keys)
- Key wrappiung with AES GCM using 256-bit key
- PBES2 with HMAC SHA-256 and “A128KW” wrapping
- PBES2 with HMAC SHA-256 and “A192KW” wrapping
- PBES2 with HMAC SHA-256 and “A256KW” wrapping
- The cryptographic content encryption algorithm used to perform authenticated encryption on the plaintext payload (the content) to produce ciphertext and the authentication tag.
content-enc-algorithmis a case-sensitive string and must be one of:
- AES_128_CBC_HMAC_SHA_256 authenticated encryption algorithm
- AES_192_CBC_HMAC_SHA_384 authenticated encryption algorithm
- AES_256_CBC_HMAC_SHA_512 authenticated encryption algorithm
- AES GCM using 128-bit key
- AES GCM using 192-bit key
- A256GCM (default)
- AES GCM using 256-bit key
- The JWE recipient’s public key. The
keyargument should be the name of a file. JWEs can be encrypted for a recipient using a public JWK or a PEM encoded public key.
- The JWK Set containing the recipient’s public key. The
jwksargument should be the name of a file. The file contents should be a JWK Set. The –jwks flag requires the use of the –kid flag to specify which key to use.
- The ID of the recipient’s public key.
kidis a case-sensitive string. When used with –key the
kidvalue must match the “kid” member of the JWK. When used with –jwks (a JWK Set) the
kidvalue must match the “kid” member of one of the JWKs in the JWK Set.
- The media type of the JWE, used for disambiguation in applications where more than one type of JWE may be processed. While this parameter might be useful to applications, it is ignored by JWE implementations.
- The media type of the JWE payload, used for disambiguation of JWE objects in applications where more than one JWE payload type may be present. This parameter is ignored by JWE implementations, but may be processed by applications that use JWE.
