Parameters
| Parameter | Description | Example | Flags |
|---|---|---|---|
| Algorithm | Which algorithm to use. Can be MD4, MD5, SHA, SHA1, MDC2, RIPEMD160, SHA224, SHA256, SHA384 or SHA512. | "SHA512" | |
| InputType | The type of input data. Can be Text, Container, Image, Path, PDF, Data, base64 or Hex. |
"Text" | |
| InputData | The actual input data. Text, container or file path. |
"Hello World" | |
| InputEncoding | The text encoding for text input. Parameter is ignored for other cases. |
"UTF-8" | |
| KeyType | The type of input for private key. Can be Text, Container, Image, Path, PDF, Data, base64 or Hex. |
"Path" | |
| KeyData | The actual input data for the key. Text, container or file path. Must not be longer than the maximum key length of the given algorithm. If key is too short, we pad it with zero bytes. |
"/Users/cs/desktop/test.pem" | |
| KeyEncoding | The text encoding for text input for the key. Parameter is ignored for other cases. |
||
| PasswordType | The type of input for the password of the private key. Can be Text, Container, Image, Path, PDF, Data, base64 or Hex. |
"Text" | |
| PasswordData | The actual input data for the password of the private key. Text, container or file path. Must not be longer than the maximum key length of the given algorithm. If key is too short, we pad it with zero bytes. |
"Hello World" | |
| PasswordEncoding | The text encoding for text input. Parameter is ignored for other cases. |
"UTF-8" | |
| OutputType | The output type. Can be Base64, Hex, Text, File, Path. Added Base64URL as option for plugin version 10.3. |
"Hex" | |
| OutputInfo | The addition info for output. For text it is the text encoding, for file container the file name and for path the actual native file path. |
"" | Optional |
