Mask common sensitive text patterns or encrypt and decrypt text with AES-GCM online for free. Review missed secrets and retain your password; lost passwords cannot recover text.
Use this tool for free without a KitNelo account. Processing runs in your browser; input limits, browser support and device memory still apply.
Automatic masking can miss custom secrets. Encryption needs at least a six-character password; a lost password cannot recover the text.
Read KitNelo data and privacy detailsPaste text and apply masking to common sensitive patterns before reviewing the changed output. Inspect names, custom tokens and unusual formats manually because automatic pattern matching can leave secrets visible in the result.
Enter the text to protect and supply a password of at least six characters to create AES-GCM encrypted output. Retain the password separately and review the saved result; a lost password cannot restore the text.
Paste compatible encrypted text and enter the password used to create it. Run decryption locally and inspect the recovered passage; an incorrect password or altered encrypted value can prevent the original text from returning.
