AWS IAM：安全拼接生成的Access Key ID与Secret Access Key

Great question! Let’s break this down based on AWS’s official specs for access keys:

First, let’s clarify the allowed characters for each key type:

• Access Key ID: AWS restricts this to only uppercase letters (A-Z) and numbers (0-9). You’ll never see special characters like semicolons (;) or colons (:) here—standard IDs look like AKIAXXXXXXXXXXXXXXXX, with zero non-alphanumeric characters.
• Secret Access Key: This key uses a Base64-encoded format, which only includes uppercase letters, lowercase letters, numbers, plus signs (+), slashes (/), and equal signs (=). Again, semicolons and colons aren’t part of this character set, so they’ll never appear in a valid Secret Access Key.

Verdict #

Both semicolons and colons are 100% safe to use as separators. Neither character can exist in either key type, so you won’t run into issues splitting the combined string back into the original keys later for credential rotation in Azure Key Vault.

If you want extra peace of mind (though it’s totally unnecessary here), you could even use a unique multi-character separator like ;;: to avoid any hypothetical edge cases—but single semicolons or colons work perfectly for your use case.
