UiPath.Cryptography.Activities.DecryptText

Descripción

Decrypts a string using a symmetric algorithm and key, or using PGP with a private key. Returns the plaintext string. The encrypted input is Base64-encoded for symmetric algorithms and ASCII-armored for PGP.

• Algorithm - A drop-down menu which enables you to select the decryption algorithm you want to use. The following options are available: AES GCM, ChaCha20-Poly1305 (Non-FIPS), PGP - Pretty Good Privacy (Non-FIPS), AES (Deprecated), DES (Deprecated), RC2 (Non-FIPS) (Deprecated), Rijndael (Non-FIPS) (Deprecated), and TripleDES (Deprecated). Select PGP to decrypt with a private key instead of a symmetric key. The algorithm must match the one used to encrypt the input.
• Text - The text that you want to decrypt. This field supports only strings and String variables.
• Key - The key that you want to use to decrypt the specified text. Used by the symmetric algorithms only. This field supports only strings and String variables. To enter the key as a secure string instead of plain text, select the field's input menu and choose Toggle to Secure input - this uses the Key Secure String property (a SecureString).

Opciones avanzadas

Opciones

• Key Encoding - The encoding used to interpret the key specified in the Key property. Used by the symmetric algorithms only. The dropdown lists all text encodings (code pages) available on the machine, with the most common ones shown first: System default, Unicode (UTF-8) (default), Unicode, Unicode (Big-Endian), Unicode (UTF-32), Unicode (UTF-32 Big-Endian), US-ASCII, and Western European (ISO). Additional regional and legacy code pages follow in the list.
• Text Encoding - The encoding used to convert the decrypted bytes back to text. Set this to match the encoding used by the tool that produced the ciphertext. Independent from Key Encoding - both offer the same full list of text encodings and default to Unicode (UTF-8). Used by the symmetric algorithms only.
• Continue On Error - Specifies if the automation should continue even if the activity throws an error. This field only supports Boolean values (True, False). The default value is False. As a result, if the field is blank and an error is thrown, the execution of the project stops. If the value is set to True, the execution of the project continues regardless of any error.

Symmetric wire format and interoperability

These options apply to the symmetric algorithms only. They let you decrypt ciphertext produced by external tools such as openssl enc, Java, and Python. Each option must match what was used at encrypt time.

• Wire Format - The symmetric ciphertext layout to decrypt. Must match the format used at encrypt time. The following options are available:
  • UiPath (Classic) (default) - UiPath's byte-stable layout (salt(8) + IV + ciphertext [+ tag], PBKDF2-HMAC-SHA1 at 10,000 iterations). The IV, when present, is read from the ciphertext stream prefix automatically.
  • UiPath (OWASP 2026) - The Classic layout with a stronger, OWASP-recommended KDF iteration count.
  • Raw (caller-supplied key and IV) - A caller-supplied key, for third-party interoperability. Requires Key Bytes Format to be Hex or Base64.
  • OpenSSL enc (Salted__ + PBKDF2-SHA256) - Decrypts openssl enc-compatible input.
• Key Bytes Format - How the Key string is interpreted. The following options are available: Hex and Base64. Required when Wire Format is Raw (caller-supplied key and IV); otherwise the key is treated as a password.
• KDF Iterations - The PBKDF2 iteration count. Must match the value used at encrypt time, because it is not carried in the wire format. 0 uses the format's OWASP-recommended default. Rejected for UiPath (Classic) and Raw (caller-supplied key and IV).
• AES Key Size - The AES key size, in bits, used to encrypt the input. The following options are available: 128-bit, 192-bit, and 256-bit (default). Applies only when Algorithm is AES and Wire Format is OpenSSL enc (Salted__ + PBKDF2-SHA256). Must match the key size the producer used; it is not stored in the wire format.

PGP

These options apply when Algorithm is PGP.

• Private Key File Path - The path to your PGP private key file. Required when Algorithm is PGP.
• Passphrase - The passphrase that unlocks your private key. To provide it as a secure string instead of plain text, select the field's input menu and switch to the Passphrase (Secure) input (a SecureString).
• Verify Signature - When enabled, verifies the PGP signature of the decrypted data using the public key. This field only supports Boolean values (True, False). The default value is False.
• Public Key File Path - The path to the signer's PGP public key file. Required only when Verify Signature is enabled.

Salida

• Decrypted Text - Reference to the decrypted text stored in a String variable for use in other activities.

• Continue On Error - Specifies if the automation should continue even if the activity throws an error. This field only supports Boolean values (True, False). The default value is False. As a result, if the field is blank and an error is thrown, the execution of the project stops. If the value is set to True, the execution of the project continues regardless of any error.
  Nota:

  Si se incluye esta actividad en Intentar capturar y el valor de la propiedad ContinuarEnCasoDeError es True, no se detectará error cuando el proyecto se ejecute.

Entrada

• Algorithm - A drop-down menu which enables you to select the decryption algorithm you want to use. The following options are available: AES (Deprecated), AES GCM, DES (Deprecated), RC2 (Non-FIPS) (Deprecated), Rijndael (Non-FIPS) (Deprecated), and TripleDES.

  Nota:

  Al utilizar el algoritmo AES GCM , la entrada de descifrado debe proporcionarse en el formato de (bytes concatenados): Salt (8bytes) + IV (12 bytes) + encryptedData (variable bytes) + Tag (16 bytes). La actividad también utiliza los siguientes parámetros:

  • El recuento de iteraciones de pbkdf2 es 10000
  • La clave generada es de 256 bits (32 bytes)

  Ten en cuenta que la clave generada de 256 bits no es la misma que la opción de entrada Clave .

• Codificación : la codificación utilizada para interpretar el texto de entrada y la clave especificada en la propiedad Clave . Este campo solo admite variables Encoding . Para obtener más información sobre este tipo de variable, consulta la documentación oficial de Microsoft.

• Key - The key that you want to use to decrypt the specified file. This field supports only strings and String variables.

• Key Secure String - The secure string used to decrypt the input string.

• Text - The text that you want to decrypt. This field supports only strings and String variables.
