tss2_decrypt(1)

💖 tss2_decrypt(1) — the decrypt girlie 💖

okay so bestie, welcome to the General Commands Manual page for tss2_decrypt(1), and let me tell you, she is lowkey iconic ✨

---

🌸 NAME 🌸

tss2_decrypt(1) — decrypts data 🫶

---

✨ SYNOPSIS ✨

tss2_decrypt [OPTIONS]

---

🦋 SEE ALSO 🦋

like, please go read these too, they're part of the lore 💅

• fapi-config(5) — use this to adjust Fapi parameters, like the cryptographic profile you're using, and the TCTI, or the directories for the Fapi metadata storages. it's giving configuration queen 👑
• fapi-profile(5) — use this one to determine the cryptographic algorithms and parameters for all keys and operations of a specific TPM interaction — think the name hash algorithm, the asymmetric signature algorithm, scheme and parameters, and PCR bank selection. literally the whole vibe spec 🎀

---

💜 DESCRIPTION 💜

tss2_decrypt(1) — bestie, this command decrypts data that was encrypted using tss2_encrypt, using the TPM decryption schemes as specified in the cryptographic profile (cf., fapi-profile(5)). no cap, that's the whole thing 🌈

---

🎀 OPTIONS 🎀

These are the available options, and yes we're going through every single one 😌

• -p, --keyPath=STRING — identifies the decryption key 🔑
• -i, --cipherText=FILENAME or - (for stdin) — the JSON-encoded cipherText 🍓
• -f, --force — force overwriting the output file 💀 (careful, she will overwrite it fr fr)
• -o, --plainText=FILENAME or - (for stdout) — returns the decrypted data. optional parameter, no pressure 🫶

---

⭐ COMMON OPTIONS ⭐

okay so this collection of options is common to all tss2 programs and provides information that many users may expect. shared bestie behaviour 💖

• -h, --help [man|no-man] — display the tool's manpage. by default it attempts to invoke the manpager for the tool, however, on failure it will output a short tool summary. this is the same behavior if the “man” option argument is specified, however if explicit “man” is requested, the tool will provide errors from man on stderr. if the “no-man” option is specified, or the manpager fails, the short options will be output to stdout 📖

to successfully use the manpages feature requires the manpages to be installed or on MANPATH. see man(1) for more details 🧚

• -v, --version — display version information for this tool, supported tctis, and exit ✌️

🌈 EXAMPLE 🌈

tss2_decrypt --keyPath=HS/SRK/myRSACrypt --cipherText=cipherText.file --plainText=plainText.file

look at her go 👑

🔥 RETURNS 🔥

0 on success or 1 on failure. that's it, that's the whole mood 💅
