Crypto

Use the Crypto node to perform cryptographic operations in workflows.

Actions

• **Decrypt** a string with a passphrase or private key
• **Encrypt** a string with a passphrase or public key
• **Generate** a random string
• **Hash** a text or file in a specified format
• **Hmac** a text or file in a specified format
• **Sign** a string using a private key

Node parameters

Node parameters depend on the action you select.

The Hmac, Sign, Encrypt, and Decrypt actions need Crypto credentials. Each action uses the credential field it needs:

• Hmac uses the Hmac Secret.
• Sign uses the Private Key.
• Encrypt and Decrypt use the Encryption Passphrase for symmetric mode, or the Encryption Public Key and Encryption Private Key for asymmetric mode.

Decrypt parameters

• Mode: Select the mode to use. This must match the mode used to encrypt the value. Choose from:
• Symmetric (Passphrase): Decrypt with a passphrase using an authenticated cipher.
• Asymmetric (RSA): Decrypt with an RSA private key.
• Cipher: When you select Symmetric (Passphrase), choose the authenticated cipher to use. This must match the cipher used to encrypt the value. Choose from:
• AES-256-GCM
• AES-192-GCM
• AES-128-GCM
• ChaCha20-Poly1305
• Value: Enter the base64 string produced by the Encrypt action.
• Property Name: Enter the name of the property you want to write the decrypted value to.

Encrypt parameters

• Mode: Select the mode to use. Choose from:
• Symmetric (Passphrase): Encrypt with a passphrase using an authenticated cipher.
• Asymmetric (RSA): Encrypt with an RSA public key.
• Cipher: When you select Symmetric (Passphrase), choose the authenticated cipher to use. You must select the same cipher when you decrypt the value. Choose from:
• AES-256-GCM
• AES-192-GCM
• AES-128-GCM
• ChaCha20-Poly1305
• Value: Enter the value you want to encrypt.
• Property Name: Enter the name of the property you want to write the encrypted value to. The node writes the result as a base64 string.

Generate parameters

• Property Name: Enter the name of the property to write the random string to.
• Type: Select the encoding type to use to generate the string. Choose from:
• ASCII
• BASE64
• HEX
• UUID
• Length: When you select ASCII, BASE64, or HEX, enter the length of the generated string. The default is 32.

Hash parameters

• Type: Select the hash type to use. Choose from:
• MD5
• SHA256
• SHA3-256
• SHA3-384
• SHA3-512
• SHA384
• SHA512
• Binary File: Turn this parameter on if the data you want to hash is from a binary file.
• Value: If you turn off Binary File, enter the value you want to hash.
• Binary Property Name: If you turn on Binary File, enter the name of the binary property that contains the data you want to hash.
• Property Name: Enter the name of the property you want to write the hash to.
• Encoding: Select the encoding type to use. Choose from:
• BASE64
• HEX

Hmac parameters

• Binary File: Turn this parameter on if the data you want to create an Hmac for is from a binary file.
• Value: If you turn off Binary File, enter the value you want to create an Hmac for.
• Binary Property Name: If you turn on Binary File, enter the name of the binary property that contains the data you want to create an Hmac for.
• Type: Select the hash type to use. Choose from:
• MD5
• SHA256
• SHA3-256
• SHA3-384
• SHA3-512
• SHA384
• SHA512
• Property Name: Enter the name of the property you want to write the Hmac to.
• Encoding: Select the encoding type to use. Choose from:
• BASE64
• HEX

This action uses the Hmac Secret from your Crypto credentials.

Sign parameters

• Value: Enter the value you want to sign.
• Property Name: Enter the name of the property you want to write the signed value to.
• Algorithm Name or ID: Choose an algorithm name from the list or specify an ID using an expression.
• Encoding: Select the encoding type to use. Choose from:
• BASE64
• HEX

This action uses the Private Key from your Crypto credentials.
