Key based Encryption/Decryption in ABAP

[Former Member]

Hi Experts,

I have a requirement where a string needs to be encrypted based on key/pwd and later needs to decrypted with the same key/pwd in ABAP.

Below is the highlights of requirement.

1. Key/pwd has to be generated and stored for encryption/decryption.
2. String needs to be encrypted with this key/pwd in ABAP.
3. The encrypted string needs to be decrypted with the same key/pwd in ABAP.

Please suggest on how to achieve this in ABAP

Thanks,

Hi,

Please check the class CL_HARD_WIRED_ENCRYPTOR.

Hi,

I checked the class 'CL_HARD_WIRED_ENCRYPTOR' but this does not align with my requirements since the string is not encrypted with any custom/generated  key/password.

Hi,

I would suggest the following:

1. Generate the password using FM : RSEC_GENERATE_PASSWORD.

2. Create an FM ZENCRYPTxxxx passing the generated key/password and string .

3. In the ZENCRYPTxxxx FM call the method ENCRYPT_STRING2STRING (concat the key/pwd and string for the parameter) from the class cl_hard_wired_encryptor and get the encrypted string.

4. Store the key/password and encrypted string into your table.

5. Similarly create FM for decrypting and read from the table based on the password and use the decrypt_string2string from the cl_hard_wired_encryptor class.

Hope it helps.

Taiyeb

Hi Vijay,

Please check below SCN link for Encryption and Decryption. But I suggest it will be good if you can get catch of any UNIX consultant and get developed UNIX script of this.
