I am trying to figure out how to use this function to encrypt a field. I figured that A5_encrypt_string(fieldname) would do it, but it's obviously not the case; A5 keeps saying wrong expression. Tried encrypt_string(), same thing. Could some on please tell me how to refer to a field instead of a text string?

Alpha Software strives to create an environment where all members of the community can feel safe to participate. In order to ensure the Alpha Software Forum is a place where all feel welcome, forum participants are expected to behave as follows:
Be sure all comments and threads you post are respectful. Posts that contain any of the following content will be considered a violation of your agreement as a member of the Alpha Software Forum Community and will be moderated:
If a thread or post is found to contain any of the content outlined above, a moderator may choose to take one of the following actions:
Moderators may also rename posts and threads if they are too generic or do not property reflect the content.
Moderators may move threads if they have been posted in the incorrect forum.
Threads/Posts questioning specific moderator decisions or actions (such as "why was a user banned?") are not allowed and will be removed.
The owners of Alpha Software Corporation (Forum Owner) reserve the right to remove, edit, move, or close any thread for any reason; or ban any forum member without notice, reason, or explanation.

Bonus TIPS for Successful Posting
Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.
When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.
The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.
When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.
A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.
If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.
When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.
Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.
- Be professional in your conduct
- Be kind to others
- Be constructive when giving feedback
- Be open to new ideas and suggestions
- Stay on topic
Be sure all comments and threads you post are respectful. Posts that contain any of the following content will be considered a violation of your agreement as a member of the Alpha Software Forum Community and will be moderated:
- Spam.
- Vulgar language.
- Quotes from private conversations without permission, including pricing and other sales related discussions.
- Personal attacks, insults, or subtle put-downs.
- Harassment, bullying, threatening, mocking, shaming, or deriding anyone.
- Sexist, racist, homophobic, transphobic, ableist, or otherwise discriminatory jokes and language.
- Sexually explicit or violent material, links, or language.
- Pirated, hacked, or copyright-infringing material.
- Encouraging of others to engage in the above behaviors.
If a thread or post is found to contain any of the content outlined above, a moderator may choose to take one of the following actions:
- Remove the Post or Thread - the content is removed from the forum.
- Place the User in Moderation - all posts and new threads must be approved by a moderator before they are posted.
- Temporarily Ban the User - user is banned from forum for a period of time.
- Permanently Ban the User - user is permanently banned from the forum.

<TBL>. Field_Name.VALUE_GET()

Re: a5_encrypt_string()
Thanks Ira; it works now.
Would you be so kind to help me understand the Key parameter. The help file gives the following expl: a5_encrypt_string("alpha software", "abc") and I am using "abc" as key without understanding what it is for, what it does. All the help file says is it's used to encode the SourceString.
Thanks

Re: a5_encrypt_string()
One common usage of such encryption is to transmit data that "cannot" be unencrypted by someone else. If the recipient does not know the key....
Code:dim ec as C ec = a5_encrypt_string("alpha software", "abc") ? a5_decrypt_string(ec) ERROR: Not an executable file ? a5_decrypt_string(ec, "def") Error decrypting string. Is your pass phrase correct? OpenSSL Description: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt
A three letter key wouldn't be to hard to break by trying multiple permutations. Longer keys are progressively more difficult to break.There can be only one.

Re: a5_encrypt_string()
Thanks Stan.
Sorry for being a pain but I' m having problem with A5_Decrypt_String() now. I have 3 fields: Name, EncName, DecrName and 2 buttons:
Encrypt button that sets the vale in EncName = to the encrypted value in Name - A5_encrypt_string(Name, "test") - this works well.
Decr button where I'm trying to set the value in DecrName = to the decrypted value in EncName: A5_Decrypt_string(EncName, "test") but A5 keeps saying Invalid Expression. I don't understand why; I am using the same principle as Encrypt button.

Re: a5_encrypt_string()
Hi Scott:
Thanks for trying to help. I am not much of a coder, that's why i use almost exclusively AS. My buttons use Set Field values in AS. The strange thing is
A5_encrypt_string(Name, "test") works in AS
A5_decrypt_string(EncName,"test") works in the interactive window, but A5 won't accept it in the expression builder in AS.

Use Stan's xbasic method. Just change the field names, etc. as needed.
